Question about 2005 Chevrolet Equinox
More than likely it is the resistor under the passenger side dash. Drop the covers under that side of the dash you sill see a 2" x 4" piece with 2 screws holding it in. It will have either a 3wire or 4 wire connector to it. This goes bad in just about all Chevy type trucks It costs about $50 - $100 at the auto parts store and takes about 30minutes to install with all the cover removal and re-installation. Once removed you'll probably see the the Circuit board is either melted or bubbled. It's bad. Also check the connector as they like to melt from overheating when the resistor goes bad. Here's a linkto what it looks like.

If the relay is good as you say, then your switch is bad. Make sure you have power going to the relay and through the relay. Did you try swapping relays with one another?

there is no relay for the heater fan it's a 15 amp fuse and is on the accessories circuit. the reostat is responsible for all 3 speeds .with the key off there should be no voltage to the blower motor whether the fans speed fan switch is on or off. the fuse will be located in the fuse paneleither on the drivers left side in the dash or underneath the dash in the fuse block. you have a short in the harness that is under the dash and most likely it's a bad plug on the harness. your going to have to do some searching but that's where the problem short is... please rate

Replace the blower motor resistor. Remove the shroud below glove box, 2 screws and a snap-pop fitting. Be careful of the courtesy light. Remove the blower moter and disconnect the purple/black power connector to it - - you'll need this extra room to work with. 2 more screws, same size, 6.5mm on mine, 7or 8mm on some others, that holds the blower motor resistor in place. This replacement part is less than 40 bones at most parts store. Unplug, replace, re-install, test and you're on your way with about 2 hours of slow paced effort in your own driveway. Typical cost at a garage - up to $400, what a sham.

In most cases this problem is caused by the rotating ribbon circuit contact under the steering wheel having a broken filament, the part is known as a clock spring contact, u will need to properly disarm the airbag and remove the steering wheel to access the part. WARNING: Failure to follow factory Airbag disarming protocol can result in an unexpected Airbag deployment and possible serious personnel injury or death.

I don't know what you mean by temp module but i'am gessing the switch on the dash, but to me it sounds like the resister is bad, i believe its located under the hood on the air box if not than chk. under the dash by the heater motor, i have seen the wires burn that plug into it when they go bad, thats what makes the blower run and also regulates the speeds of the blower motor.
