as i said it will run cold(45-50degrees) for about 15 minutes then warm up to ambient temp,ill turn it off for 5-10 minutes then turn it on and itll work again,i put a can of freon in it las night then it work right on the way to work(45 minutes) then on the way home it did the same thing just didnt come back on after i waited 10 minutes, any help?

draxcaliber

wouldn't that have to do with the a/c clutch? not he level of freon?

i replaced the ac compressor about 2 years ago when the first one went out,and shouldnt it just go out not work then quit then work again,the heat from the header would hurt it would it?

also it was running at a constant 60 degrees before and warm up every 15-20 minutes,id turn it completely off and wait then turn it back on and it would cool to 60 degrees again

if no one has any ideas about what the problem might be anybody know if the compressor can be rebuilt?

draxcaliber

then it could be the evaporator maybe.

how to diagnose, brother said evap would have to be seriously clogged, said maybe condenser before that

little help people its over a hundred out during the day here, need the ac for commuting

sounds like a sticking expansion valve. did you flush the system the last time your compressor took a ____? if not, the junk could be sticking your expansion valve.

i didnt do the replacement myself<the car had some other problems and was in the shop(beyond my skills) and the ac compressor died there, they replaced it<where is the valve,how much does it run, what do i do to rectify the problem?

TcPrincess

its either on the firewall where the lines go to the dash or on the evaporator. its not hard to change but you will have to take it in to have the system evac., flushed, and recharged.

the part usually isn't very expensive.

manifold reads 130-140 on the LOW side and 125 on the HIGH side

dont everyone jump in at once, no one thinks it may be the compressor clutch, or the low or high side pressure switch, or ac relay, compressor isnt coming on so i now it isnt the compreessor or it would be coming on or clicking but its not even coming on,
ill only have about 1 hour of daylight to check things out when i get off and dont want to be spinning my tires,my gargae has a ton of parts in it and a project car with no suspension so thats out of the question

dude people have lives they don't just wait around for you to ask questions. if you need it fixed right away then take it to a shop but don't get mad at people for not helping.

ok so tested the pressure switch
good grounds
no power into pressure switch(purple wire)
bypassed pressure switch(no change)

swapped HVAC controls
no power into compressor clutch
no power into pressure switch connector
checked a/c fuse under dash
cannot locate ac clutch relay

fixed it was a thermister junction point before the evaporator was loose, a/c is blowing a chilly 45degrees now with a 90degree ambient temp
