AC not blowing after replacing resistor and blower motor

AC still not blowing after checking all the fuses, replacing the resistor and blower motor. What else could it be? Anyone have any ideas? Thanks!

 

Did you test the fuses for continuity, or just looked closely at them?

 

Sorry, yes. Should have said that. Checked all the fuses and no issues.

 

Power going to the blower? Dumb question, but another variable to test…. If not, then did you do any mods to the electrical system at all?

These dumb trucks do wierd stuff , change something and something else logically unrelated to it stops working also.

 

Look at the connectors to see if any pins are burnt out. You can bench test a blower with battery cables.

 

Does the fan even power on? Or is it just not cold?

 

The pins are all new. The blower motor all replaced with new wires and connectors. There is no power to the blower. Could the AC knob switch be bad?

 

Now we're getting into the nitty gritty, I'd need to see the schematic of where the wires from the blower motor get power from and find the next checkpoint so to speak. Can't imagine a switch would be bad but anything's possible. Did you recheck fuses after installing the new blower? Maybe it shorted after install?

 

Hate to say this, but also check for rodent signs in your engine compartment…little shts chew on harnesses and stuff.

 

Just found out why rodent like Toyota, apparently they use some type of soy bean when making wiring harness.
