Failure Date: 01/21/2018

So I can't really drive at night as my dim lights just stop working. Yes I have brights and I have been stopped twice and ticketed once for the issue of failure to dim. This is ridiculous as they are recalling all the newer models but not the 2005. I am frustrated because I have even moved relays around but nothings helps except to set on side of highway for a couple hours before they apparently col down? you tell me.

car   Electrical System problem 8
Failure Date: 11/09/2016

The low beam headlamps fail simultaneously. This occurs while driving at night. I have replaced the hdm solid state relay twice, but after a time. 6 months to a year, the failure occurs again. Once the hdm module became to hot to touch upon failing. This last time, the third, the lights may come on again after some time has passed. It is as if the module is short circuiting or overheating leading to a short circuit.

The driver's door master power window switch module got hot & started smoking. Removing and looking at it showed that it caught on fire. It looks like it started somewhere on the circuit board.

I've just been holding onto the part because I didn't know what to do with it & the local dealer wasn't any help.

car   Electrical System problem 24
Failure Date: 03/11/2015

While traveling about 15mph through a boat yard with my heater on high (5) I smelled a hot metallic odor, but thought it was just from some welding be done on a steel boat. Then my heater quit. I turned it down to 3 or 4 and it ran a little longer and quit completely. When I got home I checked on a Trailblazer website to find information and found that the blower resistor speed control unit was a common cause of this type failure. Upon removing this resistor pack I found the plastic plug connection on it had gotten so hot that it melted and fused the plug in the socket. When I did finally get it apart I found that one of the connector pins had burned completely off. Insulation on three or four wires had also been burned. Luckily there had been no major fire.
