Aircon problems

[Mikey80]

Hi before I start I'm very sorry if this has already been covered but really don't know what to do!
I've got a mk7 accord 2.2cdti that I love to bits just having problems with my aircon I've had it regassed it's it's holding all the gas the problem seems to be no power to it I've checked all fuses and changed out the relays if I put a live wire on the single wire to the compressor it fires up fine and is ice cold just don't fire up when I push the aircon button inside the car.just to add it's the San nav head unit any help or advice would be highly appreciated thanks in advance

Have you tried the auto button on your dash and turn the temp down to low.
Also have it ever worked?

Hi yes tried the auto button and all sort of combinations! it was working a few months ago then stopped I just put it down to low gas thanks again

There is a relay actually in the headunit.
Chances are your headunit is faulty

Just to report back I've found the problem after a lot if searching and knuckle scraping it's the 3 pin connector that plugs into the pressure switch has a lose wire or a broken prong on the sensor,at least it's been narrowed down to 2 things

Hopefully an easy fix then
