Heater Question!

I have a Buddy That is needing help with his heater!

I had a lot of problems w/my blower switch on my '87 over the years. Sometimes you can rebuild them. I have replaced the blower, but it failed a little at a time. Brushes failed. Could be something as simple as a loose connector at the blower.
