As i've mentioned before in another AC thread, my 5'th gear doesnt work in my truck. 1-4 work great, but 5'th just shuts down completely. I replaced the resistor pack, but with no change. Is there any way that i can test the switch itself before i go spending more unnecessary money at this thing? It's a 2000 with normal HVAC controls. I searched all the way back to 06 and still didnt find the answer i'm looking for.

there might be a relay just for the high speed or a fuse.

5th gear? :roflmao:

5th is straight through full power to the motor. Sounds like your motor is bad. Can't handle high amperage, only reduced power. Shuts down when you give it too much power.

New motor is expensive and laborious to install, fuck it :imo live with 4th.

it doesnt... my truck has been doing this since i got it 2 years ago.

Is there a way to test the motor or probe the 12v signal out of the switch to try and track this shit down? kinda sucks only living with 4'th when it's 118 outside.

Did you replace the harness when you replaced the resistor?

Yes it is readily available. Its about a 50/50 chance when the resistor goes if it will take the harness out with it. The resistor alone fixed mine, but I could tell the connector of the harness had gotten hot. It will be the harness that connected to the resistor.
