Search Auto Parts Search '04 JGC A/C Clutch Fuse Popping Sign up here!   Email This Post Auto Repair Home>> Automotive Repair>> AC Auto Repair Help Forum jtc5740 New User Nov 3, 2007, 9:00 PM Post #1 of 4 (1913 views) '04 JGC A/C Clutch Fuse Popping Sign In I have a 2004 JGC Laredo 2WD 4.0 I6 with approx. 56K miles on it. A few months ago my A/C decided not to blow cold air anymore, and luckily at that time it was a quick fuse replacement. Now, as soon as I turn my car on, the A/C Clutch Fuse in the engine compartment immediatly shorts out. I am using the correct amp fuse. Any ideas, thoughts, repair suggestions? Any help is greatly appreciated.... PS: Do not buy a JGC. They are priced well on the lot, but that's for a reason!!!!

You can check it with an OHM meter and it should be around 2.5 to 3.5 OHMs. It's an electro-magnet and if it failed enough to blow a fuse the readings would be wildly off. Fuse could blow for several other reasons like a chaffed wire or if the wrong one YOU need to find the right amp fuse that you replaced as I don't have info on that. What amp did you replace? Never put in a stronger one in anything in a car as you should know. Owner's manual should state which fuse, T jtc5740 New User Nov 4, 2007, 9:05 AM Post #3 of 4 (1906 views) Re: '04 JGC A/C Clutch Fuse Popping Sign In Car calls for 15A, that's what I have been using. I appreciate the help, and will be stopping by the AZ today to pick-up one of those meters. If it is the clutch coil, does that mean clutch replacement or will the clutch & condensor need to be replaced? I tried my best to snake thru the car last night to try to find a chaffed or exposed wire w/o any luck. Are there any notorious spots that might be more prone to wear? Thanks again Tom...

AZ would probably have a better one than Wal-Mart for example which has a cheap and a medium grade one for only low $20 range. Handy to just have those in general. This 12v power could be overloaded by any part of the wiring after the fuse - wire itself, low pressure switch, relay, and on to the clutch. The coil failure is a bit rare to me as far as shorting but it could. The plug right at the clutch might be a problem spot. If (this can blow a lot of fuses testing) it doesn't blow a fuse with the clutch unplugged that would be a clue. You can replace that stuff without getting another compressor but it's been a long time and I forget it the coil comes with a new clutch?? I'm cheap and save all that stuff off of bad compressors when the clutches are good and ask customers (I'm retired now) if they mind a used one which was always yes for the price I offered. Try to isolate if that's the tree we are barking up first. Almost sure it will take a clutch puller tool for this vehicle which may be rentable at AZ also.
