Sweatin' in Florida

[strick's vette]

It has been a while since I have been on Corvette Action Center, but was hoping that somebody might be able to give me some Air Conditioning guidance for my 2001 Convertible with approx. 32,000 miles on it...

We just moved down to sunny Florida from Central NY, so I am relying much more on my A/C lately ad... It seems that it only gets reasonably cold when I am moving (at least 20-30 mph) and that no matter what the selection is on with the digital readout (pointed at head, feet, both, etc.) there is not any differnece in where air actually comes out from the vents. Also, the recirculate vs. fresh air does not make a difference....

I'm glad to be able to use the car 12 months out of the year now, but would like to not broil until October... HELP!

You need to pull all the codes and post them in this thread!!

Linkage Here on how to do so!!

Ya' learn something new every day.... Anyway, I pulled the codes &7 they don't appear to be helpful.... I looked the m up & they appear to all be loss of communication because of a dead battery.... I assume winterization problems... There were no codes in the HVAC section. Here's what I got:

IPC Codes: U1160 (h)
AO LDCM: B2282 (h)
2284 (h)
1064 (h)

A1 RDCM: 2283 (h)
2285 (h)
1064 (h)


Any thoughts???

Hey, I just read your bio info...

Vero Beach!!!! We're practically neighbors! We just moved to Melbourne, FL to get away from the crappy CNY winters! Cheers!

Did you charge the battery with the battery hooked to the car??? I'd try unhooking the battery and check and clean all the grounds under the hood on the frame,anything else acting weird??

There is 2 big ones under the R&L hood hinges and a couple below the battery and possibly one below the brake booster!!

I'm not understanding the reply... do you think the AC problem has something to do with battery grounding???

The first winter (god, I hate that word) I had the car a couple years ago the battery connections were very hard to loosen, so I left them on while stored in a barn. Sure enough, the battery was dead the following Spring. It appeard to have also leaked some, but no big deal- it celaned up easily on the tray... I replaced the battery & have had no electronic problems since....

Does that history help???

I do not know if the battery has any impact on the AC (I know it wouldn't on my car, but mine is not a C5).

Trust Junk. He is amazing at this stuff.

One thing to try: with the car in park rev the RPM up to 1500 or 2000 and see if the air gets colder.

In my experience, if the AC is colder at higher engine RPMs it is because the system is low on freon. At higher RPMs the compressor spins faster. This increases the pressure difference between the high and low sides of the system. The greater the difference in pressure, the colder the air.

If you have the tools to add freon yourself (I don't recommend the little throw away cans of freon with a built in gauge) then you can do it yourself. Or you can take it to an AC repair shop. If you're just low on freon, it should be relatively inexpensive.

Good Luck!!

Maybe,These cars are a little prone to ground problems!!Grounds make them do weird things,sometimes charging the battery hooked to the car can make them do weird things too!!Now in light of the other information you just gave me I would also remove the shield behind the rt front tire and check the components attached to the frame behind there!! There has been some problems with the battery's on earlier C5's leaking acid in to them!! Fact I had a buddy who's car shorted out down there and burnt his 99 to the ground!!:ugh:ughSeams like that one module under there controls some of the A/C,I'd have to do some looking!!But I believe I'd inspect the wires and plugs on all of them!!
