Chevrolet Trailblazer QuestionsRefine by vehicle
Whitout warning, my '02 trailblazer showed a "check engine" light as well as a "reduced speed" light....the car will not rev up above idle, but I ran it for enough to get to repair shop. The repair shop just called to say I needed a new throttle body. does this sound right for the symptoms I just described?
is there a reset switch or some fuse that needs reset or is my tranny goning out
gear handel freely moving then it was stop at parking,
i,am switch off its not getting start again
The owners manual shows a cooling fan relay (45) in the fuse/ relay box under the hood. The same type , & part # relay operates the headlights high / low headlights circuit (relay #46).
check engine light comes on and off it has been doing it for about 1 year. My gas hand is broken could that be part of the problem
I had one replaced post cat 02 sensor. But Im told there are 4 sensors, 2 in front & 2 in back. Now someone tells me its my air induction valve..which can cause rough idle and poor gas milege. Im confused what the heck is it?
Check fuses and they are fine, plus high beams are in working order.
the lower balljoints are worn out, sloppy front end
It gets louder when I accelerate from stops. I've seen answers to similar questions - poss water pump or fan clutch. How easy are these to replace myself? Thanks!
I have a 2002 Trailblazer LTZ with the airbag light and the phrase “Service Airbag System” scrolling across the dash in the info area. The Code reader shows only one code, and it’s B1000 which is ECU malfunction 2, according to my code reader. If you try and erase the code it says it is successful, but upon re-link it comes back. I already had myairbags.com reprogram the airbag module and get the same B1000 code. If I unplug any other sensors to the system then I get a code error for each of them. They disappear when the sensors are reconnected. I have no idea which component is causing the error. The Electronic Control module is communicating with the airbag module just fine. Is the Electronic Control module faulty? That is the module with three connectors located on the engine.
also the gauge panel tachometer bounces and the info center says to service abs. used a snap on scan toool to check the bcm no codes the vehicle than started moved it after i shut it of same symptoms any thoughts ?
My 2004 Chevrolet Trailblazer 4X4 4.2lt 6cyc. is experiencing some instrument panel cluster problems.
While driving, my battery gauge, fuel gauge, oil pressure gauge, and temp gauge stopped working and bottomed out as if I had shut off the engine and removed the key. Most if not all of my warning lights came on also. I pulled over and did a reset by disconnecting the battery. That got rid of some of the warning lights, but the ABS, seatbelt, battery, and parking brake light stayed on and the 4 gauges mentioned previously were still not working
I replaced all 6 spark plugs since they were the originals and I has 143K on them. The misfire came back right away. So I replaced the coil pack on cylinder #2, I cleared the code but it came back. I drive about 3000 miles a year, and I have been putting fuel system cleaner in with almost every tank. I was thinking of switching fuel injector on cylinders 2 and 3 to see if the misfire travels to 3 to isolate the fuel injector as the problem. I just dont know where the fuel injectors are. Can someone show me where they are? Is this a good idea?

I live in Florida and the possible ice warning was displayed and the outside temp read 5 degrees. after a few min the temp went up to the 89 degrees. after a few min it dropped to 60 then back to 83.Is there a sencer acting up. A few weeks ago the battery went dead dead. I put in a new one and little things have been happening like tis. Is it major or a miner repair.

Tryingto decide whether to just trade for something smoother. Wife has back problems.
tI've replaced the fan unit,temp.sending unit,thermostat,rad cap,water pump. Checked the rad. for being clogged(found nothing),checked the flow of coolant through the system and found that there is proper ,flow,checked for broken head gasket,checked cylinder head and engine for loss of compress(found nothing),checked vacuum(found within tolerance).What do I do now. The engine lite comes on within 2 minutes of reset. I check with my computer which has system for checking OBD systems and the same lite-code showes up. what do I do now --- Flash the computer? or what.
