When I turn the AC on the compressor sparks and.

WITH THE ENGINE OFF

A/C OFF

CAN YOU TURN THE CENTER PORTION OF THE CLUTCH A FEW REVOLUTIONS WITH YOUR HAND?

IT REALLY SOUNDS LIKE WITH THE A/C OFF ALL SEEMS TO BE FINE

WITH THE A/C ON---THE COMPRESSOR IS LOCKED UP---THE CLUTCH ENGAGES (AS IT SHOULD) THE CLUTCH (AND PULLEY) ARE UNABLE TO TURN BECAUSE THE COMPRESSOR WON'T TURN

ONCE YOU GET THE BELT OFF---DOES THE PULLEY TURN?

THE CLUTCH AND COMPRESSOR ARE 10-11 YEARS OLD......MIGHT NOT BE A BAD THING TO DO BOTH, WHILE YOU ARE IN THERE....THE CLUTCH MAY BE DAMAGED (THE SPARKING, AS IT TRIED TO HOOK UP W/ THE COMPRESSOR)

I'LL HELP YOU A BIT MORE---YOU GAVE ME NO INFO ON YOUR ENGINE SIZE--"CARAVAN" MAY BE VAGUE ALSO--MIGHT BE A GRAND CARAVAN.......IT DOES NOT MATTER I DON'T NEED IT NOW--YOU DO

ONCE YOU GET IT FIGURED OUT AND A GOOD UNDERSTANDING----REMEMBER ANYTHING OVER $100.01 WASTES YOUR PROMO'S POWER (YOU CAN'T BUST UP A $150 SINGLE PURCHASE, LIKE THE COMPRESSOR BY ITSELF--YOU HAVE TO BUY IT)......IF POSSIBLE, PURCHASE BOTH PARTS SEPARATELY---THIS WILL LET YOU BENEFIT WITH THE PROMO ON THE 2ND LESSER PART, THE CLUTCH (OR YOU CAN GET MORE STUFF TO ADD UP TO JUST OVER $100 ON THE 2ND ORDER AND MAKE OUT LIKE A BANDIT AGAIN! (OILS DON'T COUNT)

YOU GOTTA WEIGH OUT THE BENEFITS OF BUSTING THEM UP VS ONE THAT THE CLUTCH IS INCLUDED COST WISE----IF YOU ARE GONNA "PICK UP AT STORE"----DON'T EVEN LOOK FOR A PROMO CODE W/ FREE SHIPPING.......RIGHT NOW "FABU" IS/ WAS YESTERDAY, STILL WORKING

INSURE YOU SELECT "ADD VEHICLE"--INSTALL ALL OF YOU VEHICLE'S INFO---USE THE SEARCH BOX TO FIND YOUR PARTS OR PART, IF YOU'RE GONNA DO 2 ORDERS----MAKE ABSOLUTELY SURE, BELOW THE PART SAYS "EXACT FIT FOR YOUR CARAVAN"---PROMO CODE GETS ENTERED TOWARDS THE END OF CHECKOUT (WHEN YOU APPLY IT--WATCH THEM NUMBERS DROP!)

THIS IS THE SITE I USEIF YOU GOTTA USE ANOTHER STORE---SEARCH FOR PROMO CODES THEY MAY HAVE---I JUST GRAB A NEW TAB AND TYPE IN "PROMO CODES FOR WHEREVER"---THEN I LOOK THRU ALL OF THE HITS, WRITING DOWN THE BEST ONES AS I FIND THEMTHIS WORKS FOR LOTS OF PLACES, NOT JUST AUTO PARTS STORES!
