Check the wire harness that leads from the door into the vehicle, possible wiring problem at that point, if all is good there, it may be the body control module. If the other "electrical problems" are component related, it could all lead to the module.

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.

2002 trailblazer, no heat on passenger side

Probably being caused by a bad Temperature Actuator for the passenger side or a stuck mode door. Either item is a very involved repair because they are hard to get to, parts of the dash need to come out.

Passenger side windows, door locks, power mirror. on 2003 trailblazer dont work

The electrical functions on this car that you have mentioned are controlled by a module called the Body Control Module or BCM for short. Whenever a malfunction like this occurs you need to have the dealer or a well equipped shop hook up an electronic system scan tool, it will actively test the systems of the car and return fault codes indicating where to start the diagnosis of the electrical problem, in your case that can be the wiring to the door or the BCM is malfunctioning. I would be inclined to think the wiring is at fault here..

I have the same problem. I found that the stick shift wasn't locked in park possion. Once I locked it and turned the key to off the radio turned off.

Drivers side window switch not working on 2005 trailblazer .passenger and rear window switchs work but none of the drivers side switches will put rear ,drivers or passenger side down. problem with switch?

the drivers door switch is most likely bad, they get used the most and wear out first, the connector on the back of switch may have come loose and not making good electrical contact, remove switch and check connector and if still not working need new switch, the windows are all on same circuit and either all work or none work so not fuse. extremely rare is a short in wired but not likely.

My passenger window will not go down and my door will not unlock/lock with the keyless entry control on my 2002 chev. trailblazer, what kind of part do I need and how much does it cost?

you will need to replace the drtivers side master control switch module this will solve the problem. often times the contacts inside the module wear through constan t use.

Front passenger power seat inoperable

That is the power distribution center, the fuse box is under the dash to the left of the steering column under a cover, they are marked, the plastic cover will have FUSES molded into it.

Passenger electric window

Hi Ethel101
I think that what has happened with your vehicle, is that the master (driver control) switch has become defective....If you have a friend who is good with electronics you may be able to ask for help in getting it fixed....otherwise a new unit is needed.

Best regards
