Just bought an '03 Neon.. 56000 miles.. nice little car- runs great,
looks brand new :-)
However, after 2 days of limited use, the A/C quit working.
A friend of mine who knows something about cars looked at it.. he added
freon, then checked the relay..switching relays didn't cause it to kick
on, but trying to bypass it by putting a paperclip (I think) into there
caused it to kick on... so, WTF?
Obviously the compressor's working..when it did kick on it was pumping
nice cold air..
any thoughts?
He told me to buy a new relay switch today which I will but neither of
us sees how that'll help since switching out relay switches that are
identical had no effect...
Thanks for any insights..
John

Check all the fuses first. The problem is in the control side, which could
mean low freon to begin with. Did he use a gage to fill the system? Second
thing to look at is the pressure switch and its connections. Sometimes they
come loose, sometimes the switch itself fails. I'd try shorting that, too
just to see if it is at fault. The control side is pretty simple. Either
you have power to and from that pressure switch, or you don't. I don't
visit here often, okay to email me with questions. George

Dollars to donuts the condenser is shot. The guy who sold it to you
got it charged to make it work to sell. Illegal here in Canada to put
freon (of any sort) into a leaky or unproven system.
