Thread: A/C quit today

I just recently converted an 88 cadillac fleetwood brougham by just changing the compressor, putting new oil in and then filling with r134a and it blew colder than the r12 did, but there is a vacuum diaphram on the blend door that is leaking so some of the air runs through the heater core, I'm wondering if something like that happened with your car, I know it isn't vacuum controlled but something might have come loose

On my b14 in stop and go traffic I'm getting heat soak from my aluminum radiator to my condensor, I'm thinking of adding a 3rd fan that blows from the front that I can switch on when I'm in stop and go traffic, that way I can turn it off the rest of the time when I'm on the highway

Ps. What he ^ is talking about is the expansion valve there is a temp. Probe that is attached to it, once the evaporator gets to a certain temp (almost icing up) it will shut the compressor off and equalize the pressure, in doing so it will let the warm freon into the evap. To warm it up and melt any ice on it, if the evpansion valve does not operate properly the evap. Can freeze solid and I think actually freeze the freon inside of it shutting the compressor off for a while

Don't exactly quote me on that, but from what I've read that's what I take from how the a/c systems in cars work

update...I took a drive around midnight after parking the car for 4-5 hours with the hood up to cool.
Still no compressor kicking on.

coil in compressor is gone.. need new one.. or new compressor..
check your fuses one should be blown . replace it with a new fuse see if the compressor turns on.. dont be happy the fuse will pop within 2 mins and thats it.. you need a new compressor..

^^ I was going to say check the fuse.....

I'm without air right now.. it's not fun!

if u cant hear any noise coming from the compressor and it was working fine before. i can bet money its the compressor clutch or ur pressure switch. is there any rust around the clutch ? when cold turn on ac and if u see the clutch kicking on then drive it till its hot and if it stops working check power at clutch coil connector. if u have power its a bad clutch. if u dont then it might be a relay issue

not to thread jack but you from jax, fl??

just get another compressor. its not the worth trying to fix it if the problem is the compressor.

yes

cool another fwd sr20 in jax!!! i think you, matt and i should hang out one day on race day. i don't know too many b13 and b14's around here.

they are few and far between, not that I'm anti-social but I'm married with three kids, hang out time is non existent in my world. :o)
