Peugeot 306 DT 1997R (Auto air con fitted)
Fault - compressor not kicking in, nor fans, even though "green" light indicates A/C is on.
Happened once before 2 years ago - at some cost main dealer found a break in wiring?
I'd rather have a go at logically diagnosing the problem (and fixing it)
Anyone any suggestions about how to approach the problem. It more than likely is a broken wire as new clutch cable fitted very recently, which required one engine mount to be undone etc.
306 Air Con Fault Diagnosis

You could first of all supply power to the lead that feeds the clutch & see if you can hear it click in. If it clicks, remove power source immediately. Then put a meter across the terminals of the switchs on top of the receiver dryer. If it is fitted with a dual switch, one should be in circuit to tell it that it has gas in the system the other should be in circuit until there is an over pressurising when it will cut power to the compressor.
If either one is showing open circuit then either the switch is faulty or you have an internal problem neither of which will be a DIY job but at least you can point the air/con man in the right direction.[8D]
