Disconnect your battery again for about 5 mins and reconnect, your computer needs to reset

2005 trailblazer has excessive air leaks around doors. dealer claims this is normal and after 2 attempts to resolve this problem stated this is a design problem and can not be corrected.I have ridden in other trailblazers and I did not notice this problem.

I have the same damn problem with my rear door seals on my 2005 trailblazer. They came off completley so I bought some good wheather seal glue and put them on myself now they don't leak at all. Also another problem I have that I can't fix is my rear seat ripped off the seat springs 2 weeks after I bought the truck. I went to fold it down to make room for stuff in the back and BAM the damn thing ripped off. The dealer said that this is a common problem with the 05's and it could be fixed for free, but I don't have time to leave my only vehicle there for 2 weeks! It is not that bad but still bull that it happened. Other than that I love my truck. One more hint of advice to whoever would like it. I see alot of people having idle problems and such. What I did to fix this problem was easy. Do your own oil change with a good full synthetic oil that is no less than 10w 30 and not more than 10w 40, and a decent oil filter. Then only run 89 octane fuel it is not much better than 87, but the extra milage and performance are worth the extra price. All my engine glitches have stopped since I did this , and the truck runs awsome and alot more power full. I also have a K&N air filter which helps alot too. Good luck

I recently replaced the headlights on my 2004. I had to remove the front grill, which is a snap-in grill, then remove the headlight assembly. I think there were some screws to remove the headlight assembly. Once you have removed the assembly, there is a rubber seal that snaps over the light bulb. Hopefully, it is the same for '03 triialblazer.

you are right about the whole gas and oil thing.I have 05 Lt Trailblazer.When I bought the Blazer I always fill them up with 93 Octane..and the truck Ran like Crap..it seems like their computer is not compatible with 93 Octane..so STAY AWAY FROM 93 OCTANE

I am having the exact same problem, dealer wants $60.00 + to change it, the manual does not have the information either.

Same here, dealer tries to fix but still noisy. Nothing is holding the rear door trim in place and it comes loose, so I am going to try some moulding adhesive.

to tell you this but same thing happened to our 05 trailblazer. Same millage. According to what I have been reading online, many trailblazer owners are having the same problems. Get ready, ours cost $2700 to have the transmission rebuilt before we made the first payment. Now we are dealing with stalling problems that seems to be the norm among other trailblazer owners. Good Luck.

My 2003 Trailblazer LT rear windshield wiper just stopped working. The fluid still works but not the wiper itself. All connections test fine, no blown fuses.

What gives?!!??!

There is a recall for the wipers not working. Check with your dealer for the fix.

Sorry - the recall is for the front wipers I think.
