Problem #1) Sometimes it works and sometimes it doesn't. I checked the wiring by wiggling and there was no change, and the connector was nice and tight. No corrosion on the terminals and 12 volts and ground on the connector when set to full speed. If I bang on the motor, it comes to life. Assuming something internal is loose. Any chance of taking it apart and fixing that? New no-name one is $40 delivered, but if I can fix it NOW, that would be better.
Problem #2) The airflow out of the vents is pretty weak even on high. This has the electronic controller. Does this system use electric blend doors that may be stuck half way? Or after 500,000 miles, is the motor likely just worn out?
