Air con compressor not engaging

[fuqa]

Hi

Seat Leon cupra r 2003

The air con compressor is not turning on when the aircon button is pressed

I have checked power to the compressor and no power is at the plug

Is there a fuse I need to check?

Could be low on gas, I know they don't kick in if it's low but not sure if it would completely cut out power.

No power at the plug could be the fuse but could be faulty wiring or a failed pressure switch.

Without knowing the right fuse it is really easy to view the fuse panel and see any that have broken wire/blown.

Have you scanned for fault codes with VCDS?

hi

thanks for the replies

yes scanned with vagcom and no alerts

all fuses fine

i suspect it could be low pressure and thus the aircon pressure switch isnt engaging allowing power to the compressor

In that case then yeah, low pressure is probably the issue.

Had mine gassed, as was very low. However, it came out of the garage with a broken compressor and now it doesn't work at all. They just told me I have to replace the unit.

so i had the car gassed and it was a little low, unfortunately the air con still doesnt work. air con symbol stays on but compressor not engaging (no power to the plug on the compressor)

can anyone advise where the air con pressure switch is located?

many thanks

Try entering the self diagnosis mode in this thread, http://www.seatcupra.net/forums/showthread.php?t=440455 (post #5)

Some people have found just entering that mode can sort things out, even if it shows no fault codes.

If no joy from doing that, then the Pressure switch is number 9 below
