2000 ECLIPSE GT 3.0 AC

if compressor is damaged yes it could cause belt breakage --bring to another shop for second opinion

Alternator if all your wiring connections to the battery are tight

You'll have to figure out if the compressor is working when the engine is running and the a/c is switched on.
A mechanic would check freon charge and the a/c clutch circuit for power.

It sounds like you got a short circuit somewhere, you can try replacing the fuses and see if it happens again.

It sounds like your AC compressor bearings may be overheating causing excessive drag/loading on the engine. No easy way to check this unless you can take the serpentine belt off when the car won't start and see if it is really hard to turn the compressor shaft.

Look for the ac compressor,and locate the large ac line coming off the ac compressor.Follow it until you come to the ac charge port.this is where you charge it up with a charge hose that you have.Put the can on the can tap,and the quick connect to the ac port on the ac.Turn the t handle on the can tap clockwise until all the way down.hold the can upside down.start engine and turn the ac on high blower.and recirculate.shake can lightly,until the can empties.Turn the t handle counter clock wise,almost all the way out,and remove the can .Repeat to add another can,Don`t put too much freon in,and add ac oil also.If it lost freon,it lost oil,failing to do this could cause the ac compressor to lock up.One 4 oz can will be fine.look for the large ac line to get cold,and the accumulator to get real cold,then stop with the freon.

I would take it back to whoever replaced the module however, if you want to check for the problem yourself, Look for the AC compressor. with the AC turned off have someone start the vehicle, while watching the AC compressor have the person in the vehicle turn the AC on. If the clutch engages then you have lost your freon charge and need to have the AC unit serviced. If it does not start turn the engine off and check all the wiring connections going to the AC compressor. If all the connections are good start the vehicle, and have the person in the vehicle turn the control to cold and turn on the defroster. If the AC clutch engages then you have a bad ECM module or mis-programmed ECM take it back to be Properly programmed and repaired. If the clutch does not engage it is possible the AC compressor is bad. Take the vehicle to the Mechanic to have teh AC system checked to see why it is not engaging.

Sounds like the cooling fan motor,or motors,are not working.Check the relays,and fuses for the cooling fans.If the ac is on,look to see if the cooling fan,or fans come on.If they do ,then most likely have an enternal ac system problem.The expansion valve is the most likely problem,or possible,the dryer.Have the ac system checked to see if it is low,or if the low side is going into a vacuum,if it is going into a vacuum,replace the expansion valve.First check to see if the cooling fans are working with ac on.If I can help,let me know.>>>[email protected]

Cant be good abd could do damage.. I would take no chances.. If the noise came right after deal work,, take it back and have e'm check it..

Clean the trottle body and air bypass valve, then disconnect the battery for 5 minutes, this should cure your concern.
