A/C Clutch fuse blowing
rebranger posted a topic in 1999-2013 Silverado & Sierra 1500I have a 2004 Z71, 5.3 V8, auto. All of a sudden the A/C clutch fuse began blowing. Disconnected connector on compressor, NO fuse blowing. Replaced A/C compressor, vacuumed & re gassed, A/C works fine for about 30 min, then blew another fuse. Removed plastic bottom shield (shroud) to get to wiring harness which was grommet-ed (attached) to around exterior of oil pan/block junction. Removed protective plastic wire shield. At the juncture of the wiring harness split on the passenger's side, the wires were very warm to the touch, no smoke, no burned wires, no shorts that I can find. It appears to be a bad connection in the circuit or a bad sensor somewhere. Anybody have any ideas of what/where to check next? PCM under hood had a 10 amp fuse, replaced it with a 20 amp, A/C ran a while (20 min, normal driving) then blew again!! Does the engine temperature sensor (drivers side towards front) have anything to do with this clutch control circuit?
I have a 2003 Suburban Z71 that I just converted to electric fans. I used a factory wiring harness that I found on ebay, and the fans turn on when the temp hits 190. The truck was tuned by a popular tuner, but the fans will not kick on with the A/C compressor. I have wired in both wires to the pcm connectors. I cannot for the life of me get it to turn on with the A/C compressor. Could it be a bad relay? Could my 2003, not be able to control the fans when the A/C kicks on. I have fried my compressor, and would like to get this figured out before spending money on another. Does the tuner need to turn on the capability for the fans to kick it on? @JennabearI didnt use your tunes for this as I had another option at the time, but I need some answers. If you guys can turn it on, then you will have my money today. Anybody else have any ideas?
My 2001 Suburban is exhibiting some strange behavior recently. The ABS light and brake light recently came on (getting some help on that on this thread: http://www.gm-trucks.com/forums/topic/152470-abs-light-and-brake-light-showing-up-at-once/?do=findComment&comment=1343182) and now my wife called me with the following news. She was driving it this morning, and while she was driving, the a/c was blowing nice and cold. But when she stopped at the light, the fan continued to blow but no cold air was coming out. She also said that the idle seemed to drop just slightly, to around 500rpm (while she was in drive, with her foot on the brake). Once she started up again, the a/c resumed it's cold temp. Some facts that might be relevant: It's a 1500 series with a 5.3 liter motor. The battery is 3 months old. I tested the alternator at the same time, and it tested out fine. The serpentine belt is under 3 years old, and appears to be in good shape. The vehicle has 187,000 miles on it, and has the original a/c compressor. Generally, all of the maintenance that needs to get done has gotten done over the last 9 years we've owned it, so it's been pretty well-maintained. Any thoughts on this? Also, should the idle be that low in drive? With the a/c on, my wife said it felt like it was going to shut off. Thanks in advance, David
