Dodgy Aircon

[rojtatton]

Hi all

Having a bit of fun with my aircon, its a 2.3 ford galaxy ghia dual aircon year 2000 mk1.

Had my local aircon peeps round and they checked it out for me, its got gas and it does work... intermittantly.

And when it does its very cold.

So its not gas or compressor or pressure switch(replaced it). had the condensor and some pipework replaced last year as well.

heres the kicker i have noticed it cuts in when going up and down hills.

now im suspecting a dodgy earth or wiring somewhere. but where....

location of wiring and connectors for the aircon would be greatly appricated or any other hints as to whats causing it.

I believe that this can happen if you do not have the correct amount of gas in. Up and down hill does seem to support that. When I eventually found someone with the kit and who knew how to use it, the first thing they did was to put it on a full test cycle which apparently takes up to an hour or more. They cannot tell how much gas is in there without taking it out and vaccum testing it and putting the right amount back in.

 

They do this with Bosch equipment and charge

update time

took it to fraud main stealers yesterday.

had to have it gassed (yeah riight). stll didnt work

and put power to compressor all works fine, so it was electrics like i told them.

they chased the wiring and found an earth on the pcm?

ended up putting a switch in that earths but has aircon running all the time, but i thought climate control did that anyway unless you hit the economy button.

i was there 7 hours and it cost

For the sun sensor, I found mine on the middle front next to the windscreen, how you get to the wiring - you'll need a very very small person to crawl in under the dash or it looks like a very deep strip of it
