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?
I have electric fans on a 06’ Sierra 6.0. Twice in the last 2 months (or so) I’ve had them not turn-on when they should have been on. I happened to notice because I could smell it running a little hot and my temp gauge was all the way to 210-ish. I switched on the heat to help dissipate the extra heat. When I started the truck up a few minutes later the fans turned on and all was well. (not that it should matter but I was at 8-9K ft. both times. I know this impacts the coolants’ properties but I wouldn’t think it would have any impact on the fans themselves) The only work that’s been done on the truck lately was some fluid flushes including the coolant. Seems unlikely that this would be related but thought I would mention it. Prior to me realizing it was the fans, I tested the coolant to ensure that the dealer put the right mixture in and it tested fine. The first time this happened I thought maybe they disconnected the fans during the flush process but verified that the connectors looked fine and since the fans have been running since, I ruled that out. What do I need to check next? Seems odd to me that its intermittent. Seems like it’s a sensor type issue of some sort but that doesn’t quite click for me since the gauge is reading fine. Could the thermostat be acting up? I couldn’t quite wrap my head around how that would influence the fans…. Let me know what y’all think I need to check next. Much appreciated! Sam
My neighbor's '98 Silverado 6.5L had been running in the 215-225 range ever since he rebuilt it and put on the full Banks turbo kit. He changed to an aluminum radiator and bigger fan. Still ran hot. Just put in Flex-A-Lite's dual fan/radiator kit to see if that cured the heat issue. Dropped operating temps to 195-200 even sitting idling on a hot summer day here in Mississippi. Has anyone else tried one of these radiator/fdual-fan kits?
