the ac on my 99 rodeo is out this summer. i don't think it's the
in the fuse/relay box under the hood, i unplugged the ac relay and
plugged it back in and the compressor came on. but it only lasted while
i was testing it. the next day the compressor wouldn't come on again. i
charged the system, so i know it's not low on coolant.
i've heard it may be the low pressure switch? is this something that
can be replaced?
You can test the pressure switch by jumping the wire contacts. It's on top
of the evaporator.
How do you know the leak isn't so bad that the refrigerant wouldn't leak out
overnight? Follow the a/c lines and look for greasy areas near fittings.
Is your fan running properly when the AC is going? I had a problem with my
Dodge Caravan - I think it ended up being a relay or 2 bad, but the fan
wouldn't kick on. The AC would run for a short time and then kick out
unless I was at highway speed. I realized the fan wasn't turning on when I
turned on the AC like it should. Unless it was running at speed, there
wasn't enough air to keep things cool and it would shut down. Not sure if
it could be anything similar as the Caravan uses electric fans, and unless
the Rodeo is different from the Troopers we have, the fan is belt-driven
from the engine...
yes, the fan seems to be fine. i'm thinking now it's a loose connection
i try turning it on while driving, and sometimes it comes on, and
sometimes it won't.
doesn't seem to be any leaks. when it does come on, it's as cold as it
