Problem with my 2003 Chevy Trailblazer ls
5.3 V8 large

GM Computer codes = No
Repairs done prior = No problems except for the back passengers side
window does not work to up and down but no major work.


GM tech = JK
question = My car dies when i turn on the a/c or heat, it's fine when it's just
running, and i am also losing some power with the buttons on the doors with
the lock and unlock button, there is no other problems but the rpm's dip way
down below one when idling with the a/c on, then it catches itself, but
eventually dies, this only happens when idling, it does not die when driving.
This sounds like a very common problem when there is carbon buildup in the throttle body bore and plate.

Suggest a good cleaning. The throttle body is the front top of engine that the air cleaner duct hooks up to.

Remove the duct, open the throttle blade, spray some carburetor or carbon cleaner from any parts store
all around the bore and plate.
Then spray some on a rag- not a paper towel, and wipe all around the bore and plate.
Re-install duct and start the engine. It will run rough for a few second. Rev it up a few times to "Clear it
out".
Then take for a short ride doing a few hard accelerations.
Shut truck off for 2-3 minutes, then start ans let idle.
After this, the idle should be fine."

The window problem may be in the switch itself. If this is the problem, a new switch would need to be
programmed after replacement
2006 Chevy Trailblazer. Engine size = 4.2
Computer codes: P2432. Question = how do I fix it and where do I get the parts.
Answer: This code is for the Secondary Air Injection Pressure
sensor circuit voltage low. First
check the fuses labeled "Air
Pump"  and "Air Sol", and swap the "Air Sol" relay with a known
good one. They are all in the underhood fuse box. If fuses and
relay are good, you need to test for voltage at the
AIR solenoid
valve on the passenger side of the motor.  The PCM controls the
relay and the valve. Most likely the valve is faulty, since the
pressure sensor is internal to it, but you need to make sure the
valve functions first. Would not just guess at replacing it.
