Defroster yes, heater no.

It is coming on with the ac and defrost. it comes on and shuts off every few seconds. Does this mean my compressor is no good Or can I just tighten something. this happened 1 day after I fix my heater core is that just a Coinsidence? Can it hurt my car if I drive like that Without using the ac? Here is a link to a video of the problem http://www.youtube.com/watch?feature...&v=1G5CIg2WJLI

Can't watch the vid while at work but it is proper for it to cut on & off. Every few seconds (as you describe) seems excessive.

No, it won't hurt anything to drive it without the AC or Defroster running until you figure out what's wrong.

It sounds like you have too much charge on your freon. You'll have to take it in to have the system checked then maybe evacuated & recharged.

The video posted is really short, but it cycles on and off a half dozen times during it -- almost the definition of compressor stall. It seems controlled, though, as if the computer is turning it on and off, versus something like a broken wire or something.

Have you flipped through the the tech manual? Starting on page 1A-61 is a quick test that involves looking at a little sight glass to get and idea of the fill. The other tests involve gauges and VOMs. In short, there's a little cannister to the right of the radiator, with a circular window on top that allows you to see the coolant moving. You should see a few bubbles that disappear when you rev the engine. If you see foggy, foamy, or nothing, then you've got refrigerant problems.

The AC is active when the defroster is on -- AC pulls moisture out of the air, which makes it effective on foggy windows.

Being right alla time is really starting to wear me down.

Glad it was a simple fix for you.
