Hello!

I wonder how the AC clutch should behave? Mine goes on for 10 seconds and then it's off for 10 seconds then it connects again for 10 seconds and does that when standing still and the engine is warmed up to normal temperatures. It comes cold and warm air inside. The engine is a LT1 -95.

Thankful with any input!

Most likely its low on freon /134a

You can run the self test on the climate control see youtube. But sounds like your low on freon.

Ahhh ok! Can I drive it like this without anything happening or should I have it off?

Best to not have it cycling on and off all the time, parts wear out and the A/C clutch is a bit of a PITA to replace.

Ok great! Will see how much they take to refill it and if it's a big difference from the DIY stuff out there I'll go for that one.

I get it for $50 a case but you can get it for $7 to $15 a can at local stores. One can should do the connector about $15 just get the simple one the gauge one is a waste. Or you can get a can with the built in deal. Spit in the valve good chance that is where your leak is. You can replace the valve without loosening freon with the right tool. Or just get a new cap with a good seal will help.

Tip would be to go slow with it as well.

Like add maybe 1/4 can, drive it a little to see if it helped, then go for another 1/4 can.

My first time doing this with one of those cheap single gauge kits...

Now I have a full manifold and vacuum pump, but I'm still just tinkering around.

Go slow, run it for a bit, let it equalize/settle and add a little more.

If you end up having to bleed it out you can loose some oil and it makes it a larger job.

I just add till it stops cycling then hold the cold line when I feel the cold flash I stop.
