I would think there is a problem with a sensor which my be an IAC Sensor. That makes the idle air control Hi or lo depending on what the motor is calling for. Have a shop take a computer reading and see what sensor is bad, As for the air There is a Air condition Amplifier and there may be a problem with that its not common but sounds like it may be the problem with your trailblazer. I sure hopes you out Flash68, If not get back to me and we can trouble shoot some more. Take care Bear001

Truck should not be driven when the check engine light flashes, means you have something very wrong. Take it to a place like Autozone, they will check the code (check engine light) for free. There will be a code on the print out they give you, starts with Pxxxx. Let me know what the code is. What was done when you did the tune up?

Air cond on 2002 trailblazer

This has been a regular problem on the 4.2 vortec motor. Usually the Throttle Body has to be cleaned. Even with as many as 30K miles. Easy process.. When you do this you must unhook the neg battery cable to reset the PCM. They make a throttle body cleaner (different than Carb/choke cleaner). You can get it at any parts outlet. has a article describing the whole process step by step. Takes about 30 minutes. Do a search in the article section under throttle body cleaning
