Electrical System
Faulty wiring harness that burns under the dashboard/glovebox on the passenger side (feet area). The harness controls the blower motor fan speeds 1,2,3 setting and has a resistor. The wiring harness/loop begins to melt and subsequently burn. My passenger brought it to my attention after it singed his shin; i unplugged the wiring loop prior to catching on fire. There are many online complaints at chevy colorado…

The relay for the brake lights under the dash has failed 4 times on my chevy colorado. The last two failures occurred after the part was replaced with the supposedly redesigned part from the recall. When this happens the brake lights fail to operate and no indication is given to the driver. *tr

Several times over the past six months i have been left stranded temporarily by my colorado not cranking. There seems to be no rhyme or reason to it. Some days it cranks fine. Others, it may take as long as 45 minutes and several attempts to get it to start. I have found many fellow colorado owners have had this same issue and it seems to be caused by a faulty pass code switch/sensor in the ignition. I believe that…

The cooling/heating blower fan speed resistor and wiring harness on the 2004-2009 chevy colorado has a shorting problem which causes the truck to have a smoke smell and may lead to a fire if not checked on. I found mine after smelling smoke for a few months and started checking where it was coming from. I found the fan speed resistor connector and associated wiring harness burnt and slightly melted. I would have…

This has been going on for about 3 years off and on. On average, about twice a week, when i try to start my car using my original factory keys (i've tried both with same results) the security icon lights up and the truck fails to start. I then have to wait 10 minutes for it to reset. I've contacted gm about this problem and they have told me to take it to the dealership after that happens. When i was finally able to…

The hvac fan motor resistor & connector melted around one of the prong connections and wire. The resistor and wire harness are located just under and behind the glovebox on the passenger side. The result of the burning of these parts is that the blower speeds of 1-3 do not work but 4 still functions normally. This problem is more than an annoyance of the fan setting because the cause is melting wires and burning…

On 23 june 2010 i was driving my 2005 chevy colorado to work when i began to smell burning wires. I shut off my vent fan switch and the smell went away. I turned it back on and the smell returned. Later after work i found a charred wire connector and resistor next to the fan motor. The resistor had been previously replaced in 2006 when the vehicle was under warranty. There are alot of posts on-line from owners of…

1. Normal driving. 2. Brake light switch failure. Brake lights inoperable along with inoperable cruise control. There were no consequences, however having no brake lights could result in sever consequences. One has to wonder if a wreck had occurred would it be considered my fault since my brake lights not functioning was the cause of the wreck? 3. I replaced the brake light switch with a new gm part purchased at a…

The blower module wire harness continually goes out. I have replaced it twice and the same thing happens. Appears to me that there is some sort of short in the wiring. If you take off the bad harness and look down in the connectors one of them is always burnt up. I worry that it could cause a potential fire hazard. I know that i am not the only person that is happening to. I continually check internet blogs and it…

Since that time the vehicle intermittently stalls immediately after starting and requires several attempts to restart and keep running. Security system light is on.

Blower motor fan speeds work intermittently. Fault was found in blower motor wiring harness where harness runs adjacent to glove box. Jostle the harness manually below the glove box and the blower motor speeds will go from off to only a few speeds to normal. This could definitely be a fire hazard. *tr

Changed the battery. Causes the door switch to go out. The driver's side window, the door locks and keyless entry will not work. You need to hope the window is not down if you change batteries or have a dead battery needing a jump start. The dealer charged me $400 for a new switch. A check of the internet shows many many people have had the same problem. *tr

The passlock anti theft system on my 05 chevy colorado failed this winter leaving me stranded out in the cold for a half hour or more on multiple occasions. To reset it you must turn the key forward and wait ten minutes, then repeat that two more times before it will reset and then the vehicle will start. However it takes a special type of scanner that a dealership must plug into the internet to reset the code so…
