Another Blower motor
One of the items on my list to fix on this 79 is the heater blower motor, it didn't run when I got it. Before I started on th work on it, it started to work and it stop again.
So I thought I would focus on it this weekend, I must have left on the mid speed setting. I turn the key it started working, I switched it to high. It stopped, I switched it back anf port from low to high. All I hear is click in the engine bay.

I would look into an issue with the relay and it's associated circuits

The photo is what mine looks like, this is what was posted by someelse in the forum.
It has the blue Red and the purple wires, the one on the link had a ground in place of the purple wire.

I thought I would post the fix for my blower problem. I look for that relay in the photo I posted, what was turning up at the parts store is not what I have. What I have is called A/C Cut off relay, insalled the new relay now I have a blower with full range of speed.
