What does it mean if im driving and everytime i turn on the ac my steering would vibrate and then stop and once in a while it would vibrate again. Thiis only happens if i turn on the AC.

 

That's your compressor kicking on every now and then. it's normal.

 

its vibrates hard.. like when you have a warp rotar and you are trying to stop at 80mph.

 

its normal.

 

I can't sit in your car so i don't know. my car sometimes has trouble idling with the ac on, but it's just because the compressor adds a load to the engine. If you think something is wrong, check the belts for clearance, and listen in the engine bay for what it could be. it may be the compressor seizing , but if it's cooling I highly doubt it. Does your engine regain it's RPM's after a moment when it kicks in at idle? Is it at speed, or at idle?

 

Might be normal is something is worn ..
But a perfectly working a/c system will not vibrate your steering wheel.

 

does the serpentine belt have anything to do wit this?

 

I would think not since our cars don't run serpentine belts.

A serpentine belt is a single, continuous belt used to drive multiple peripheral devices in an automotive engine, such as an alternator, power steering pump, water pump, A/C compressor, air pump, etc. The belt may also be guided by idle pulleys, and/or belt tensioners. --- Wikipedia

Possible causes: bad compressor, worn idler pulley bearings, low idle while a/c is on, bad engine/tranny mounts, probably more, but I am tired.

 

o man this sounds bad. My car idles around 800 and it doesnt jump.

im guessing yours is a high mileage car. Like has been said before, its normal. Try blipping the gas when this is happening, and the car will stop shaking. On small 4 cylinders ESPECIALLY hondas for some reason, the A/C being on makes the car shake. Sometimes more than what seems normal. Check everything out, but if the A/C is blowing cold air, your compressor is probably fine and so are your belts. Older cars start idling rough due to idling lower as carbon builds on the IAC passages. Clean out your IAC with sensor safe throttle body cleaner. Dont mess with your idle screw. No matter what some jerk tells you. It wont do any good. If anything, bad things will happen. Or just let it shake. Whichever.

 

i have a 98 ls gsr with a 00 gsr swapp. miledge is around 80 - 90k.
