Replying to: HopeGMC (Feb 04, 2009 11:34 am) Thank you HopeGMC. I talked about taking the truck in 2 months ago, but still never found the time, and because my other car has been buried under 2 ft of snow. I tried the relay thing today, and as soon as I put it back in the truck, everything started working again. So you saved me more inconvenience, and probably some money... Well at least for now... But thanks for the tip, it was greatly appreciated... It will be so nice to have power door locks again, AND TO BE ABLE TO GO TO A DRIVE THROUGH, OR ATM....

Replying to: HopeGMC (Feb 04, 2009 11:34 am) Hi,   I'm having just the door lock problem (no window problems at all) where my doors will not unlock with the key fob but they will lock with it and the doors lock and unlock normally from inside of the vehicle. The key fob is good because the lights flash when I unlock the doors with the fob but it just doesn't trip the unlock mechanism. Also, if I do not unlock with the fob first, the alarm sounds when I use the key to open the door. Oh, and one other thing that I noticed is that when I remove the key from the ignition, it doesn't unlock the doors. I could have sworn that it used to do that.   Anyhow, if you have a schematic of the system I would love to get a copy from you. I have the wiring diagram from a car maintenance book but it does not have a schematic... just a wire going in and a wire going out, etc.   Other than this one problem, the truck has been real good. It's excellent on gas and has plenty of get up and go.   Thanks for any help. Cheers.
#165 of 248 brake lights by diddysmash Feb 12, 2009 (7:05 pm)
I have a 2006 gmc canyon with a 2.8L. It just now hit 30000 miles. i have had no problems until now and for some reason my brake lights won't light up. The funny thing is that my third brake light works fine. I have replaced the bulbs, checked all the fuses, and have even traced the wiring as far as i can see it but cant seem to find the problem. I contacted the dealer and got the usual BS ($80 per hour) has anyone had the same problem or have any suggestions on what to do. Replies to this message: HopeGMC (Feb 13, 2009 5:03 am)

Replying to: snaproll1 (Dec 24, 2007 11:48 am) Snaproll,   You are describing exactly what is happening to my 2005 Chevy Col I5 Ext 72K.   The problem is deep cycling the battery kills everything under the hood. I have changed out batteries twice now. First time was at around 55K when the original battery gave up the ghost, massive overheat and death.Second time was an 860CCA battery that lived about 6 months with two accidental drain outs. No, you don't need a "special" battery from the dealer.   I noticed you said you run a cooler through the ACC adapter. I run a 500W inverter all day in my truck, sometimes engine on, somtimes not. I power a laptop that draws like Vegas and charge camera, radio and cellphones batteries. I've had this vehicle from new and it was fine before I started using it for work. Apparently the regular deep cycling doesn't just 86 the battery but also kills off accesories and ultimately larger parts. My blower is now only working on level 4 (sound familiar?).   So I spent $200 on a Yellow Optima Deep Cycle Battery and we'll see how that goes. I spose I'll have to replace the blower motor.

Replying to: Alennx (Feb 20, 2009 5:14 pm) Running an invertor can do damage to the old battery real quick. Thats why RVs with convertors run 6V deep cycle batteries that are made of charge/discharge and then if you let them go below 50% they become toast quickly too. Your lucky it hasn't got your alternator yet with all the drain on the battery makes the alt. run overtime.
#171 of 248 2005 Colorado flipping out by duart Feb 23, 2009 (7:40 pm)
This truck is having several electrical problems. It cuts out while driving sometimes to the point of stalling the engine.The tach has very erratic movement. The radio sometimes looses its presets and the clock returns to 12:00. The blower fan also acts up with only high speed available. all this gradually came about overnight. No service codes. All these problems come and go. Sometimes they all are evident, sometimes maybe one or two are showing up. It has never failed to start.
