Remove the top cover. Remove the coils. Replace the plugs. Simple. You will need 10mm tools and a spark plug socket

I have a 2002 Chevy Trailblazer LTZ that has climate control and it just suddenly after getting fuel the drivers side air condition is working but the passenger side is full heat and cannot get it to

There is an actuator on that side. Pull the plug and put it back in, see if it works. If not, then you will need a wiring schematic to check for power and ground. If both are there, replace the actuator.

I have a 2002 Chevy Trailblazer LTZ, Might be a trans problem....

Have it scanned and see if there isn't a trans code. If it is spinning out between gears that is called slippage. There is not much you can do since there are no adjustments. The only thing that it could be other than the trans itself is a problem with the TPS, Throttle Position Sensor, and if that is defective and you don't repair it right away you can do serious damage to the trans. (almost 30 years rebuilding trans and 4 of them directly for GM. I know the 4l60e extremely well) Do not drive this if it is slipping. Hope this helps.
