I've always heard that Dodges were notorious for this. It has something to do with when the a/c condenser kicks on. Mine does the same thing from time to time.
lol i have been a technician for years and i didnt know a condenser could kick on.....last time i checked it had 0 moving parts whatsoever....i am assuming you mean compressor.....
Oh wow, I vaguely remember posting this last night. I was kinda wasted.
But anyways, I have stock MM and it still kicks in hard. At idle my car is smooth and doesn't vibrate. I figure as long as it blows out cold air then all is good. I noticed that if I shift into neutral immediately after turning on the AC, the ac doesn't kick on as hard as when I have it in gear. So that's what I do from now on.
On another note, stay away from bicardi 151.
Ah man. I use to drink that stuff straight out the bottle.. Lol, yea it'll kick your ass if your not use to it..

This is the first summer with my srt, and the AC kicks on harder than any other car I've ever driven. It takes a couple of seconds for it to kick on after turning it on, and then I can feel it. I remember the first time using the AC I though I ran over something in the road because my car basically jerked really hard and made a noticeable noise.
So, is this normal?
When the compressor clutch first engages, mine does the the same loading down of the motor and the belt makes a little screech noise like stepping on a dog.
I try to engage the AC when sitting still and idling. It seems to reduce the loading effect and does not give out an "arrr!" from the belt slipping when the compressor clutch first engages. If driving, push in the clutch, let the motor idle, turn on the AC. After it engages, resume your speed.
I was a rental agent (secret) for 2 years in Phoenix, AZ. When it was 120 deg outside, in the shade, the Dodge/Chrysler AC's always worked the best out of all of the cars. They do a good job with coolin' down the cockpit.

Reason: spelling
Mine is getting bad. At cold start, i turned the A/C on and the engine just died due to the load.....
Donno what makes it so hard to turn, but definitely, when the A/C has not run for a while, you start it and you hear a screech along with the "roll over a dead body effect"....lol
If you start the A/C everyday it still "kicks in" but not as brutal as if it has not run for a week or so.
Not supposed to be normal... the running over dead bodies part..... yes with inserts or solid mounts you will feel it engage, should be a quick clunk and its done... I had my compressor replaced due to it engaging as you described, the technician first said there was absolutely nothing wrong and said I was imagining it... So I went back there with his service manager and had them both watch the belt as I turned it on. Both of their jaws dropped and the manager said it'd be replaced and then apologized for the tech's comments. It worked fine for about 2 months and started acting up again. I didn't bring it back simply because their techs don't know squat about a/c systems (I worked soley on automotive a/c for more then a few years ) Good luck!

According to Dr. Who in a previous A/C noise thread, he explains what that grinding noise is, and yes, it is normal....

This is to maintain the lubrication in the compressor circuit and avoid hydraulically locking the compressor if the lubricant pools down in the compressor.
Even with all of that software wonderment, ocassionally when the compressor clutch engages, the compressor has higher than normal resistance due to the lubricant pooled in the compressor... This makes the clutch slip and it 'grinds' for a second... Subsequent A/C clutch engagements should be quieter since the lubricant will be distributed throughout the Refrigeration system...
