Latches/locks/linkage problem #1

We were on vacation and we were getting ready to leave and we tried to unlock doors to enter vehicle and all doors except the driver door unlocked. A passenger leaned over to unlock the driver door and hit the driver window down switch. The key was not in the ignition. A burning smell was noticed and the driver door was completely dead. We were able to open the door and drive the vehicle. When I returned home I popped out the driver door module and noticed that the plastic case was melted. I opened the unit and noticed that a wiring harness connecting the 2 printed circuit boards was completely burned. Luckily this did not cause a major fire.

Latches/locks/linkage problem #2

Vehicle was parked for the evening, turned off, no key in ignition, and unattended. Driver door module worked fine the previous day. The next morning, no parts of the module worked. Upon investigation, we discovered that the left side of the module by the driver window button had a burn spot on it and smelled like an electrical fire. The dealer quoted the part only price as over $300. 00. Updated 7/31/12 the dealer replaced the door lock module. Updated 08/01/12.

Latches/locks/linkage problem #3

Vehicle was parked with all doors locked and the vehicle not running. The remote unlock button was engaged and all doors unlocked with the exception of the driver door. The remote unlock was engaged 3 to 4 more times. The door was manually unlocked from passenger's side. When the door was opened, smoke was pouring out of the inside. We poured available liquids down the window slot but smoke was still pouring out. While my spouse went inside the business where we were parked to grab a pitcher of water, I jerked the plastic oval piece around the inside door handle off and saw flames. He returned with the pitcher and we poured the water down the open hole at the door handle and finally managed to extinguish the flames. We drove the vehicle home but none of the door functions worked at all. It is going to cost me approximately $600 to fix this issue. I have been afraid to drive my Trailblazer since that time. Also the fuel gauge quit working about 3 months ago. We finally fixed that issue today. The next issue to repair after the door is the heat/air actuator as the air conditioning no longer comes thru my air conditioning vents. . . Updated 08-27-12 the consumer also stated the fuel gauge stopped working. Updated 08/28/12.

Latches/locks/linkage problem #4

Vehicle is a 2007 chevy trail blazer, purchased in July of 2007. Over the past several days, the driver's side power switches on the door were not working properly. Vehicle was parked on Friday evening at around 6:30 pm and when car was entered on Saturday morning at approximately 9:30 am, the drivers side door was on fire and black smoke was billowing out. The fire department was called and disabled the vehicle so there would be no additional damage. They stated that it looked like an electrical short in the door panel.
