2005 Chevrolet Trailblazer Interior lighting Problems

“My headlights and dash lights flicker while driving. Also while driving my lights will dim and the blower for heat & A/C will slow and then pick up to normal speed again. It also revs by itself, even in park and will go forward slightly when it does surge. These problems only started after the alternator was replaced. I think it is a safety hazard to have lights flickering and engine surges.”

“Just want to address the gas gauge and speedometer issues. I have a 05 Trailblazer and had both of these problems. Fortunately I work with a great dealership and I purchased the extended warranty because GM would do nothing and the fixes are very expensive. …”

“Chevy trailbazer 05... Gas gauge keeps moving from low to empty back to full,sometimes it stays at empty. Check engine light stays on. Fuel sending unit keeps failing. Unit was replaced in 2007 at dealership. Sending unit has gone bad again. Very expensive labor needed to fix this. When I fixed the first time I had warranty now it has expired. I checked online and it seems like everyone with a chevy Trailblazer is having the same problem also my..to my knowledge this is a completely defect of the car. My major fear is to run out of gas on the highway and my car to stall. …”

“While driving above 30mph, if take foot off accelerator, headlights will dim to almost no light as will the dash lights, on off, on off, when press on the accelerator, lights will go on normally with same brightness. Dome light button to left of steering wheel will work once every 50 tries, lights on left side of radio do not work, cd player will not take cds. I am unable to drive my vehicle at night, it has been to a certified Chevrolet dealership twice now, they have stated that everything is running correctly and that they cannot find anything wrong with the vehicle. …”

“Headlights dim intermittently, heat looses power at the same time, now getting flickering of interior lights. Wasn't able to fix it. Bumper warping. Getting 10 miles to the gallon! Paint on buttons wearing on radio. Sun roof leaked profusely, had it fixed. Rear window defogger doesn't work. Head liner sagged.”
