A/C related problem

[aalambert]

I have a 2000 Galant and the air conditioning started to get pretty weak last summer. I had my dad recharge it. Since then, the car does some weird things that seem to be associated with the AC. Whenever the AC is on, the car will vibrate (pretty violently) in short spurts during acceleration. (I have never driven through them, I've always taken my foot off of the gas and it stops.) Sometimes, a lovely screeching noise will also accompany the vibration.

The vibration will also occur when the car is in park and the fan kicks on, but for maybe less than a second.

Also when the fan kicks on, the RPM jumps and the car will sputter if I've been driving for a long distance (50+ miles). Again, these issues only happen when the AC is on, and after it was recharged.

What could possibly be causing this?
Thank you!

Sounds like your compressor is shot.

What are the operating pressures?
How much charge was installed (grams/ounces)?

Was this an off the shelf bottle to AC system thing like RedTek?

Or was a proper machine used, following evac and vacuum down period?

Fan/s both operate properly when they are supposed to come on?

I would consider having a mod move this post to a more appropriate home where we can delve into this more.

Also, check the condition and tightness of your belt(s) for your skretching condition.
