Hello all,
1st edit, this is a 1993 K1500 Silverado with a 5.7l V8 and 3 speed air conditioning blower.
So I finally got my Air Conditioning working, I replaced hoses, condenser, and pretty much every moving part under the hood except the compressor. It would only blow on high but living in Florida that was good enough until I got around to replacing the resistor which I have read causes the other speed to not work.
Yesterday I went out and started the truck to take it to a friends house to work on another project and the AC was not working at any fan speed. On the drive I hit a solid bump and it worked on high again. Once I was ready to return home it did not work again, today I took the glove box out and went to Napa to buy a new resistor. I installed the resistor and still nothing from the fan, you can hear a slight click from the resistor area when you change fan speeds but nothing from the blower.
I do not have my multimeter with me so I tested it with a 12v tester, all fuses are good. The motor is getting voltage as I pulled the purple wire and tested it. So I feel like this could be 2 problems:
1. I still have a weak ground from the motor to the firewall, that is on my list to be replaced next.
2. The blower motor? Maybe it has died?
So my next steps will be to replace that ground and test, then replace blower motor and test.
Am I on the right track here? Thoughts?
