A/C finally works

Finally got the A/C working today. Looks like the only problem was low on charge. When I got the vette, the owner told me it did not work but did not know why. I just assumed the system had a problem and put it towards the bottom of the to do list. Well it works great now. No more sticking to the seats in August

Hahaha just in time for Hot Tennessee Nights   Thats great, good job Glen

Very Cool !

Okay it's a bad pun, but still a good thing.

 I had an aftermarket a/c installed a short time ago. It blows cold air.....no problem there. My question is... should it pull the idle down 400-450 rpm's when turned on at idle? If I have it on and stop, like at a light, I have to feather the gas or it will likely die.  The installer did mention that I may have to put in a solenoid to kick up the idle when it's turned on. Sound right?  Of course they also said that the reason my headlights and wiper cover now come up when I turn off the motor is because the check valve going to the vacuum canister and dash didn't work.  Not worried about the vacuum right now, but whadda ya'll think about the a/c. I'm gonna need that to work right in June!

I don't have a solenoid on mine and it idles fine. It will drop the rpm a little when the compressor kicks on. I am not sure how much but will check it out and let you know. Can you set your RPM a little higher to compensate?

 I have it set at about 1000 rpms now to keep it from dying when I turn it on.

Many cars did use an idle kicker solenoid.  Some did not need them.  But the way your idle drops, it would be a good idea, and solve your problem.

It just mounts at the front of the carb, and uses the same power wire that goes to the compressor.  When the A/C is on, the idle kicks up.  The factory ones kept the idle up the whole time the A/C was on, not just when the compressor kicked in.

 Thanks Ken. So you thinks that pretty much normal to drop 400-450 rpms when the a/c is turned on?

Way to go Glen...........!

Hopefully I will be able to say the same soon.

Dwain,

I just checked my RPM drop when the A/C compressor kicks on and it only fell 60 rpm. My system is stock with freon. I did notice a connector on the power wires to the compressor clutch which nothing was connected to. Maybe come years used the solenoid like Ken mentioned.
