I have a 2003 Chevy Traoilblazer that is having multiple problems.
1.Instrument guages are showing innacurrate readings (ex: false fuel readings, 10 mph speedometer reading, oil pressure displaying excess pressure)
2. When AC is on the truck will stall out when we come to a stop
3. Ignition Coils are going out every other month
4. Auto Transmision slips during first drive of the day.
I have had the truck looked at and repaired at least three times over the last two weeks!

I have a 02 trailblazer that I had to have almost the entire engine rebuilt after it hit a little over 90k miles. Now, after having the O2 sensor on the exhaust somehow come disconnected and melt the wireing harness replaced, I have been told the a damper or something in the camshaft is bad and I have to have that replaced which will cost me around $2k(again like rebuilding my engine). The worst part is that this was replaced when i had my engine rebuilt. Now after about adding 50k miles or so it is happening again. I want to know if someone might have some other ideas on what could be wrong cause I am tired of spending money on this **** vehicle. The vehicle has been running on extremes amount of gas(using a tank where it should use 1/2 a tank). They said it was the o2 sensor but after it was replaced it still wasn't running right and now the mechanics say that I have to replace the dmaper or something in the camshaft or driveshaft or something. The worst part is that I am stationed in Korea and can't be there to see whether its BS or not. Any ideas anyone?
#642 of 665 A/C Problems after battery replacement.
Jul 28, 2011 (4:37 pm)
I have a 2003 Chevy Trailblazer LT 3rd row 4.2 Ltr V-6. I replaced the battery today and everything was fine before hand, but right after instalation of the new battery the driver side A/C blows weak and only hot air qall other vents blow cold. it has the dual climate control (manual not digital) and rear air. I have had this happen once before 3 years ago when I replaced the battery. There is a climate control reset sequence that fixed the problem last time and I can not find it online anymore. Does anyone know it???

The whine is getting louder and I noticed she is losing power. I am at about 47K. Just had the oil changed two months ago and OnStar says I am at 60% oil life.

I'd check your battery ground strap for tightness and cleanliness; also see if you blew a fuse or a fusible link.

I'm having trouble with raw fuel dripping from the intake manifold on my 2003 chevy trailblazer. The problem pointed to the fuel pressure regulator, I purchase one/ install it problem solved. Now after one day it has begin to drip again. Any suggestion.

Try to disconnect the battery again, for 30 minutes or so. Hook it back up and see if this clears it up.
