2003 Chevy Trailblazer ls 5.3 V8.

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

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.
Answer:
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

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.

Question = I took my truck to get the ball joints fixed.when I pick
it up later on that day as I drove and turned my ac on ,my truck
turned off on me. Now when I drive and I turn the ac on and
come to a stop my truck turns off. And I never had this problem
before.i took it back to the place that fixed the ball joints and they
say we didn't touch nothing but I didn't have this problem before
I took it to them. I need advice.
Answer:
I can;t see anything about doing ball joints that would cause your
stalling problem. See the above answers for cleaning the carbon
from the throttle. That is probably your problem. If they
disconnected the battery, that may have affected the idle with a
throttle full of carbon.
