The Alternators primary function is to keep your battery charged. As well as that, it also provides your car with all of the means to be able to run things related to electricity. A tip to look out for, is lights can be dimmer, wipers slower and various warning lights on the dash because low voltage can cause many systems to fail.

Air Conditioning Widnes

Air Conditioning WidnesHere at Widnes Auto Electrical services we are experts in repairing everything electronic in a vehicle, this includes your vehicle’s Air Conditioning unit, but if yours is working fine, you may feel that you don’t have any requirement to get it serviced, but Air Conditioning can go faulty without you actually noticing (unless you know what you should be looking out for). Here at Widnes Auto Electrical services we can repair & service your Air Conditioning unit for your car throughout the Widnes area.

Why do I need to service my vehicles air conditioning if it is working fine?


  • The right amount of refrigerant and fresh oil will improve the efficiency of the Air Conditioning system and can increase the life span of the compressor.
  • Cleaning air intake ports in the vehicle can clean out the water drainage pipes together with bacteria treatment, as this prevents the Air Conditioning system from mould build up on the inner walls, which is the reason for bad odour coming into the car when the A/C is on, and may cause health problems to yourself or your passengers.
  • An efficiently working air conditioning system may improve your vehicles MPG (Miles per gallon).


My climate control system only blows in warm air. Will an Air Conditioning service, procedure or recharge fix this?


Yes and no. If your system is low on gas, then a recharge should get the system working properly. But any other faults in the Air Conditioning, like gas leakage, electrical or any mechanical component fault(s) need to be diagnosed first and eliminated before recharge can be done, as this could cause more problems further down the line for yourself.


I recharged my Air Conditioning unit one month ago and now it’s empty again. Can you come out and find the leak?


Sadly, no: A micro (very tiny) leak can be very hard to trace, the wind and sun complicates the work of the technician and in some cases can extended the diagnostic procedures required. Leak finding test can be done solely at our workshop, located at the industrial area located under the Runcorn Bridge (Widnes side).


How often do I need to get my Air Conditioning system serviced?


The majority of vehicle manufacturers usually recommend to service the Air Conditioning system every two years. The cabin’s Air Filter usually has to be checked always during each annual maintenance service and must be replaced if required. Vehicle air conditioning can present unexpected and unexplainable problems such as: Heat that doesn’t heat up the inside of the vehicle. Air conditioning that doesn’t cool you down during those awful stuffy days in the car. Defrosters that can’t keep the windows clear, these can cause safety issues when driving in the winter. Unpleasant odour, this is usually caused by a build-up of mould in the inner walls and this causes the air to push the strong smell into the car forcing yourself and your passengers to cope with the smell.

The old classics!



Two old classics in this week with wiring issues. The Porsche 944 had sunroof issues, the customer had fitted new motors and switches but the fault remained. Broken wiring turned out to be the problem. With the Morris van the customer had stripped the vehicle to respray and had put the wiring back incorrectly and had burnt the loom. So we cut out the burnt wiring and worked out where they had wired it wrong and got it up and running. Two happy enthusiasts picked up their pride and joys ready for the summer.



Today in our workshop this JAG XKR came in for a softtop conversion. These lovely machines strangely never came with remote operation as standard. With this conversion the owner now has full open facility where all the windows come down and roof opens with 1touch of a button on the key fob and the same for closure. Also the internal roof switch is now 1 touch rather than having to press and hold it for the duration of the roof operation. One happy customer was now looking forward to a sunny bank holiday weekend with the roof down.

2012 Renault Master


This Renault Master came in this week with heater blower trouble. It was quickly diagnosed as a faulty blower motor and speed control module. The diagnosis was the easy part. To change the motor the whole dashboard had to be removed as seen below. But with our experience in these type of jobs once the parts were sourced it was fitted and reassembled quickly so the customer could get back to work.




Into our workshop this week was this nice little car with abs faults. It had been into another garage for diagnosis and a rear abs sensor had been fitted, but the fault remained. The garage had then fitted a wheel bearing hoping that would cure the fault,but to no avail. So the lady came to us upset with this garage because they had fobbed her off having taken a load of money off her. So we started our investigation by plugging in our diagnostic machine and confirming the fault which showed up as a rear near side sensor open or short circuit. So the next step is to see if we are getting any signals at the sensor. We found one of the wires to be open circuit so now it’s a case of tracing the wirer back and finding the break. The cable runs up under the back seat then along the sill to the engine bay
. We removed the front passenger seat and exposed the wiring and found the broken wire in the sill. We bought a replacement loom repair section from SEAT cut out the bad section and refitted the carpet,cleared the fault codes and road tested to confirm the repair was good. A happy customer picked up the car knowing where to come in the future with electrical problems.


Summer is on its way


2010 VW Golf

Into our workshop today was this VW GOLF with electric window trouble. We diagnosed it as a faulty mech and as you can see on alot of vw’s the door has to be completely disassembled to fit a new mech, not one for the faint hearted!
But another successful job and another happy customer.


2012 Skoda Superb

This lovely Skoda came into Widnes auto electrical today with the electrical problems with the electric boot release and closure. With these cars the boot and glass can be opened separately and in this case the glass wasn’t opening at all. So the first problem was to release the glass so we could gain access to the wiring. To do this we had to dismantle the locking mechanisms on both sides of the boot, which we did(not an easy job!!) then we could strip the covers off the hatch and access the wiring loom. We did our checks and found broken wiring in the hatch. We removed the loom from the car and replaced the damaged section and then began the process of reassembling the vehicle. Which took awhile but you have to make sure the locking mechanism is put together in the correct order or it just won’t work. Again the customer picked it up the same day fixed at half the price they were quoted from the agent. One happy customer



This 2011 B180 was brought to our workshop this week from another garage which couldn’t get to the root of the trouble. The problem was it was blowing a fuse intermittently which was then bringing on the battery light and management light. The previous garage had plugged the diagnostic into it and was getting a fault code relating to the stop/start alternator. The strange thing about this fault was that the fuse that was blowing was not listed as controlling the alternator circuit. The first thing we would normally do is to disconnect the alternator and see if that stops the fuse from blowing, but in this case the wiring is inaccessible unless the alternator is completely removed from vehicle.
The alternator was removed and checked and found to be ok. So we started to look more closely at the circuits that were controlled by this fuse even though they weren’t coming up on the diagnostic!
The circuits all related to the lambda sensors, purge canister solenoid and swirl flaps.
We could easily disconnect the lambda sensors and see if the fuse blew, which we did and found that the fuse still blew. The swirl flaps on this vehicle were vacuum operated so we couldn’t see how that would pop a fuse. But we got access to the control for the flaps and found we could move them very easily as a common fault with these is they can seize up due to oil and soot from the engine.
The only option for us now was to examine the loom from the main ECU in the engine bay, as wiring to this could affect unrelated circuits which might use a common positive connection. After a few hours of careful examination of the main engine loom a tiny nick on a cable which was not directly connected to any of the devices that was on this fuse or alternator was found across the top of the engine. The wirer was reinsulated and the loom refitted correctly so as to not cause problems in the future. The car was road tested and given back to the happy customer.
