Kimberly Smith: Water pump problem is due to weight of fan clutch being too much for the short shafted water pump, wears out the bearing. If you get the code telling you your smog pump and egr valve needs replaced, check the relay located along the frame under the driver's door before replacing them, is the problem that sets off the emission codes. GM master mechanics will charge you nearly $700 to replace the other parts, and will continue to replace them everytime your check engine light goes off because that is all they are trained to do.

Tracy Christensen: my 05 tb also has simular issues. Just had the water pump replaced last month and they guys are out replacing the vent blower moter relay under the glove box as we speak. My speedodomer also broke this week and my gas gage hasnt worked in over a year. My rear windsheild wipers keep slowing down and I think the hose has become loose as it does not squirt anymore. When I first got it we had to replace the berings on the front pass tire. I love this car but sheesh.....
angela mcdonald: Yes, I am having the same problems with my 2005 TB. My dash is all messed up. Speedometer, oil gauge, fuel gauge. Water pump went out in July of 2016. Around the same mileage. I think they have computers in vehicles so that when the vehicle hits a certain mileage it is programed to disfunction a certain part so as to have to buy parts. Reckon???
YUR_1_TRU_FLY_WHITE_GUY: At my house we got a 02 Chevy trailblazer and a 03 Chevy trailblazer and they both are in good shape we also got a 99 dodge Dakota mine. And a 08 Silverado all of them are decent but the 03 trailblazer has been chuckin 02 sensors Idkw
james pontonio: i have a 2005 trailblazer as well i am haveing an issue with the rpm gage and gas gage gm had recalled them for that i have no other issues with it
TheTruthSeeker 02: its a moter in the cluster
Angel Camacho: if you take good care to your car he will never leave you on the road 😎
UcD xKHAOSx M: my 2005 trailblazer's oil pressure gauge doesnt work and my speedo every now and then bounces a little on and off of my actual speed
TheBayArea831: I have a 2005 trailblazer ext and I love it. Had it almost 11yrs and im currently having alternator issues. But thats normal wear and tear. It has 133k miles. We have always used full synthetic oil. Still runs like the day i bought it. Very smooth and comfortable. Fits 7 people. Im happy with mine and plan on keeping it for as long as i can.
Rubberhead Studios: same problem in my 2004

A Ray: I've been having problems with my brakes on my 2003 Chevy Trailblazer LT with 4.2 liter. The pedal feels really spongy and the ABS/service brakes dash light comes on every time I drive it. I looked at the pads and rotors and they seem fine except the rotor in the front is a little rugged, but OK. I bled the lines for air and still the same issues. I replace the master cylinder, bled lines again and still the same issues. I don't know what to do anymore and I've given up so I guess I will just go around the internet and ask people about it. Thanks for any help. Peace.
Halt1jacob Conner: my 2005 trailblazer 2x4 has 223,000 miles on it and still runs perfect and when you floor it it flys
Annette Rome: Eriik, what should a 2002 chevy trailblazer be driven on 4w hi or ??????? what should i drive it on?????
linuxman777: the Trailblazer worst car I've ever owned. Jumped to Ford and have had fewer problems.
Drunken Ocelot: they had a recall on the gas thing
tam nguyen: My 2005 trailblazer has blend door actuator problem front and back. Have to tear the dash apart to get to the actuator. The transmission failed at 56K. I bought the extended warranty for $2,500 so it cover the transmission.
foxstan: I have a 2005 Trailblazer also. There are problems that are a result of poor engineering but maybe that is why they quit making them. Overall satisfied. We had several gauges quit working. The gauges have plastic gears that strip. We sent the entire gauge cluster to a shop in Canada that replaced the plastic gears with brass and we have not had any more gauge problems. The front main seal failed on a trip to California and a dealer there replaced it. Engine light was set because the thermostat had failed open and the engine did not heat up in the prescribed time frame. Can't just buy a thermostat but must buy a hose assembly with the thermostat. Yesterday it failed to pass emissions and from my research may just be a blown fuse. Who in their right mind links a computer anything with a cigar lighter which has a heavy inductive load? Seems like it would cause a voltage drop and spike. Anyway, computers should be on their own circuits. Will probably follow Patrick Brown's advice for the next passenger vehicle. Chevy and Ford are lacking good engineering and quality in important areas and refuse to step up to the plate and fix them.
