91 q45 a/c operation

1992maximase30 · 08-16-2009, 06:30 PM

whats up.
i'm havin a lil problem with the a/c in my 91 q45.
it was low on charge so i recharged it.
it was fine for the 1st 3 days then the condenser fan went out then the a/c stopped working.

so i went to ghet another fan and another condenser but it's smaller than the oem fan but still blows a good amount of air.

i recharged the system again.
it's gets cold then gets air temp a few seconds later.
the compressor works.

the sight glass shows the fluid going through.

i'm about ready to give up on this and take it to a shop, but i dont have that kind of cash.

can anyone shed some light on this
thankyou

theres a way to put the climate control inside the car into diagnostic mode, i just don't remember how, try looking it up on google, if you get it to do that it'll get you a code as to whats wrong

why dont you take it to a shop and have them give you a detailed est
then do whatever they were going to charge you for

i bet its a fuse

1992maximase30 · 08-24-2009, 08:58 PM

nope. no fuse.
the compressor turns on.
the display works. no a/c codes.
the temp door is working fine. the air flow doors work.

it's just that when you first turn it on it gets cold the room temp.
