air con VP
Can anyone help me
i have a vp calais with climate control my air con works fine but it seems to cut out for too long about 15 to 20 sec. The air starts to get warm then it kick back in it doesent seem right to me
has anyone got any ideas can throw my way, I have changed the sun sensor and it's not the problem. Now I am going to change the climate control unit. The dignostics chesk says that the sensor are fine. Stage 3 shows 31 vent and console is it suppose to show. Please I need some help to fix this.

Perhaps it might be just a bit low on refrigerant or the pressure switch is faulty. When you first turn on the A/C does it get cold quickly or does it take a while?

I thought I was wrong once but I was mistaken.
it takes awhile and refrigerant has been looked at and is fine anso is the pressure switch

check to see if your thermo fan is cutting in and out

Is the compressor actually cycling on and off with the temperature fluctuation?Originally Posted by vpcalaishsv
If so, there are two possibilities. Either the low/high pressure switch is being activated or the climate control is deciding to cycle it.
I would establish which by monitoring the voltage before and after the pressure switch. You could connect leds to these and have them in the cabin to see what happens when you are driving(if the problem doesnt appear at standstill)
Voltage disappearing before the pressure switch indicates climate control/electronics/sensor problems, after the pressure switch indicates charge problem or switch problem.
i have looked at all of that and it work like it should.Now i have found there are 2 pipes that go into the dash. the biger 1 from the accumulator witch is not as cold as the 1 coming from the evaporator.
