How do I get the high speed back on my heater blower motor? Ever since I deleted the A/C, I only have low and medium speed. I still have the a/c relay wired through and would like to eliminate that as well. My diagrams do not show that very well. Any help with this is appreciated.

You needed to keep the wiring from the original setup.

You use the a/c box resistor pack and wiring which has a high speed relay.

I didn't change the resistor...same one that came with the car...I would have had to splice a new plug if I changed resistors.

then you should have a large square relay right next to it which is for the high speed. If it's still there, you have a switch or relay problem.

OK...I bet it's the relay...it just flops around in the engine bay... Laughing

Pull the relay out and jump the motor and battery terminals of the plug together. Fan should go on high. If it does then it's the relay, if it doesn't then it's the fan motor, switch, or a wiring issue.
