Default Blower Motor Resistor and Connector problem

on high blower is ok for a couple hours then stops blowing. I turn it off and wait 1-2 hours then it works. I think maybe the resistor connector is corroded.

Agree.. I would just toss a new resistor in there. $15.

I checked the connector to the resistor &did not see any corrosion. I replaced the resistor and after about 1 hour the blower’s velocity is minimal. I shut the a/c off and waitied 30-40 minutes and then the blower starts working properly again. The evaporation coil does not freeze up restricting flow.
Not sure where to look now! Any suggestions?

On my 2013 the blower motor was bad. It would work properly sometimes and then just quit.

I should have added they load checked the blower motor and it was pulling more than 30 amps causing the relay to reset.

Replaced the resistor and still had exactly the same results. Worked ok for about 45 minutes and then on high it basically stopped blowing. Waited about 39 minutes and then it start blowing on high again.

I checked the connector and there was no sign of corrosion. Could it be the blower motor or maybe a problem with the control module????

Any ideas?? Would greatly appreciate any help!
