It is now the beginning of September and the car air conditioning season is almost over. We still get problems, though. A Vauxhall Vectra came into our garage in Halifax, with the air conditioning not working.
In recent times(during a hot spell) we have had a few Vauxhall Vectra cars in with the air conditioning not working.
One guy, the owner of a Vauxhall Vectra GSL found that when he pressed the air con button in the car the revs dropped on the engine, but there was no cold air coming through into the car?
We discovered that he had a plug connection to the compressor that was not connecting properly. The compressor was failing to engage, because of the faulty connectors wiring. We repaired the faulty wiring and the compressor started to engage. The system worked fine and the customer went away happy.
Another Vauxhall Vectra came into us with her air conditioning failing to work. We tried to re-gas the system but the air con system was not holding the gas. On inspection with our leak detector, we noticed that there was a hairline crack on one of the pipes that were coming from the compressor. This pipe was causing her all the trouble. We ordered a new pipe, fitted it and re-gassed the air conditioning system. Once again the lady went away happy with her air con working to perfection.
The Vauxhall Vectra is also prone to having a damaged condenser.
This is located at the very front of the car and looks just like a radiator. To get to the compressor, you have to remove the whole body panel. When the customer brought in the car, he told us that his aircon was out of order. The first thing we did was to check for leaks with our special fluid. The leak test bought up a leaking condenser.
It looked like the condenser had been hit by a stone and was damaged. This is a common Vauxhall Vectra fault because the condenser is exposed at the front. We fitted a new condenser and re-tested the system before re-gassing it. After the re-gassing the air conditioning
the system worked fine and the guy went away a happy bunny (the day was a scorcher)
