Heater problem
2006 Chevy Trailblazer 6 cyl Four Wheel Drive Automatic 43000 miles

I would like to know if anyone can help me. I will try to make this short. Resistor went bad for the blower motor on my 06 trailblazer. I changed it and it seemed to work fine for a few minutes then no forced air from the front vents on any speed. Clicking noises from near the climate controls coincided with the failure. One of the receptacles on the wiring harness leading to the resistor is slightly melted (the plastic around it not the metal itself). What could cause this? All fuses check out ok. What are the parts called associated with the climate control. The knobs all the way to the motor including the wiring itself? I cant seem to find any info anywhere other than the resistor and the motor itself. I am sure of one thing, I need some parts, just don't know what to ask for

Here is some info, Some customers may comment that the blower will only work on low speeds or has become inoperative. REPLACE THE BLOWER MOTOR RESISTOR AND RESISTOR MODULE CONNECTOR. Lower the hush panel or close-out panel enough to gain access to the resistor module connector.
Disconnect the connector from the resistor module.
Remove the tape from the wiring harness to expose the wiring. Cut the wires back far enough from the connector to eliminate any melted insulation on the wire. Install the new connector. Use the yellow splice sleeves provided with the connector.
Install new blower motor resistor.
Reinstall the fuse or connector block. Test the blower motor to make sure all speeds are functional.
Reinstall the hush panel/close-out panel.
This bulletin might help. Here is the part #15862656
for the connector.

I can't thank you enough for helping me figure out that I only need to change the connector part# 15862656 and not the whole octopus of wire its attached to. I had nightmares about my dash, instrument panel, and various other parts laying everywhere just to get to it. The part number was especially helpful to be able to find a new one at half the dealer cost.

I included a picture for anyone else out there with this type of problem looking for this connector. I also found out that this part also has an AC-Delco part# PT2195
