When I'm driving over 45 mph the rpms start jumping up and down while the rpms are at 2k and during that time the truck starts to stutter , some times it doesnt stutter while driving.

Cruise control and air conditioner actuators quit at the same time, what could my issue be? I have replaced the turn signal and the brake switch and have also checked all fuses in the fuse box under the hood and under the seat all are fine. Any help would be greatly appreciated. The sooner the better please as I would like to have this fixed before summer gets into full swing.

The Trailblazer's battery dies when it isn't started for a day or two.when it doesn't turn over & the key is shut off ,there is a sound in the area of the CD player. Sounds like it's trying to release a CD. We bought the Trailblazer about 6 months ago & never put a CD in the player. The Trailblazer also came with a CM2000 Corrosion Module. could a malfuncution in this unit cause the battery to die?

The light turns on by the dial but that's it and you can hear it click on in the motor but other than that it don't work front or back what could it be

We have had 2 Chevy Dealers & 1 local repair guy... tell me 3 different things for this A/C problem. Who to believe???
Can hear AC condenser clicking on & off while idling, have blower that blows out at all speeds & on forceful the recirculating button below radio.
Have been told 1)recycling switch problem, 2) when had a brake line rupture - braided line had been rubbing on something & rubbed a hole in brake line leading to zero brakes one day! We had asked the repair guy to look at the A/C issue also & were told that the A/C line had been compromised by the brake line as well - small pin hole leak now in ac line, 3rd) driver side actuator problem. All quoted about $500++ to fix it.
I went online and found a video on the actuators. I pulled drivers & pass. side(s) dash trim apart lightly. (Removed the plastic colored trim coverings for the dash area.) I can see the actuator on pass. side working. I can see one of the actuators high up above the gas pedal... it has the little circular dime size ring move when I turn the knob that changes the flow of the air from feet only to feet & chest, to chest only, and to defrost. I believe then this the mode actuator. Down below this about 6" & right next to the black vent line that runs across the bottom of the whole driver area - I see another actuator where the little ring thing that is supposed to move.... but doesn't move whether a)I move the air flow (Mode?, or b)whether I move the driver side toggle button that changes the temp. from colder to hotter. I have the diagrams from GM on the locations of the three actuators on this side, but can't find another one. I'm thinking the 3rd actuator is the defrost actuator and it must be way up inside and behind the mode actuator. Knowing we've had 3 different people look at this AC issue, and knowing what I've I told you.. what do you think? Do you think it's a driver side temp. actuator that needs to be replaced? Please advise!

ok so we changed the shift cable in october worked fine now just yesterday my car wouldn't start but would turn over like dead battery finally started but when got home i turn it off and key got stuck in igntion and gear shift was in park but dash was reading 3rd gear so wont let turn on or take key out finally we replaced the gear shift and then took off column cover and used the button to release the key.

Have to push and pull out a lot to get it to lock in and to exit the seat belt have to push the button 4-8 times to get it to eject.

I recently took my 2005 trailblazer to a dealership for pricing towards another vehicle. The question arose concerning the scheduled maintenance of the timing chain and if I had it done. I was not aware that a timing chain had to be replaced unless there were problems with performance related to the timing chain. Is this a scheduled replacement at 50,000 Miles?
