It will not switch from outside air and inside air.

every time I turn the key, after about 15 seconds it burns out the cooling fan motor relay. This part right here:

After this relay burns out, there are no lights in the dashboard. no ignition, no click, no power. Also, it drains the battery. if I try to jumpstart it afterwards, I get an explosion of sparks when I hook up the alligator clamps to the terminal. Not fun.
Here is a list of what I've tried so far:
unplugged the blower motor
ripped open the harness and dashboard, sifted through piles of multi-colored spaghetti, found nothing. (so far. more suggestions in this department are welcome)
checked every fuse, none are blown. which makes no sense. why does it burn out the relay instead of a fuse or in-line fuse?
I haven't recieved much help in the way of wiring diagrams, all of the ones I've found are really simple or partial and don't go very far in depth.
Any help at all, or gut feelings, or comments are greatly appreciated! this thing's been out of commission for a month and a half. The damn thing doesn't even have an electric cooling fan. (or did it? maybe someone before me modded it.. I think it has a thermal clutch on the fan) ]]> GM Electrical Tech Merkatroyd http://www.gmtruckclub.com/forum/showthread.php/122947-Cooling-fan-motor-relay-burning-out!-(88-Chevy) http://www.gmtruckclub.com/forum/showthread.php/122864-License-plate-light-not-working-help-before-I-get-pulled-over!!?goto=newpost Fri, 10 May 2013 02:29:55 GMT My drivers side license plate light is out, passengers side still works fine.

It is worth noting that I had an aftermarket white LED light in place of the OEM one. These bulbs burn out rather quickly, so I replaced it with a brand new aftermarket bulb. No reaction. I then replace it with a OEM bulb that I am 100 % is in good working condition and I still can't get it to work. So it looks like I am driving around with only one license plate bulb on until I get this fixed! Does anybody have any suggestions on what this might be.. some kind of shortage, perhaps?

Give me some tips before the police ding me on this!

It is not the same as a 1999 or 2000 suburban, apparently in 2000 the denali was the only suv that gm put a BCM in. My neighbor's locks stopped working. The BCM is clicking when I press the button, the switch is good. I would like to checkout the relay but can not find it. I have found diagrams saying that it was behind the glove box. I have exhausted my google abilities. The one I found was for the blower fan.

I want to use a relay kit to make BOTH these filaments come on (high + low beams) rather than choose between the 2...... in the desert you need wattage...
has anyone done this? im worried that it may cause the bulb to bust... though it never seemed to be an issue on my jeep
any input or discussion would be great.

I have a 2005 Silverado with a 4.8 Vortec. This truck has 199,000 miles and I recently put a new motor in it and had the transmission rebuilt. Except for rebuilding the transmission, I did the work myself. It's been running well and I am real happy. About 1500 miles after the engine swap, I was driving one night and the engine died, the doors unlocked (as if I had turned the key off), but the engine came back on, the doors re-locked and the truck resumed normal operation. This all transpired in probably less than two seconds. I spoke to a couple of people who are familiar with these trucks and googled my problem. The thing I kept hearing was that It was possibly a bad ground. I have checked the ground strap from the firewall to the back of the engine and the ground cable from the battery to the block. Those connections are tight and without any corrosion. I also read to check the two ground wires at the frame beneath the driver's door. There is no sign of corrosion there either. I continued to drive it without any issue for a couple of weeks until recently. It did the same thing with the engine cutting in and out and the doors unlocking and locking, but this time it occurred multiple times in succession. This time the information center flashed to have my brakes serviced and my brake light and ABS light have come on in the dash. I got the truck home and it has sat while I have been driving my car instead. I read where a ground wire beneath the battery can cause this problem but I pulled the battery tray completely out and there is no ground wire there. There is a ground wire coming from the negative cable on the battery that runs to the front bumper support on the drivers (battery) side and this connection looks solid but there is some corrosion. I will have to pull the lower bumper cover to properly clean this connection. Has anyone else had this problem? I really don't think the issue is related to the recent engine swap as I drove it without any problem for several weeks. Any suggestions would be appreciated. ]]> GM Electrical Tech 05Silverado4.8 http://www.gmtruckclub.com/forum/showthread.php/121443-Phantom-Electrical-Issue-2005-Silverado
