Thank you for using, my name is XXXXX XXXXX I will be happy to assist you with your
concern today.

Just seeing if you still
need assistance with this problem?



Customer: replied 4 years ago.

Yes, I do

Have you connected a direct 12v battery hot to the blower motor as a bench test and seen if it spins faster? The reason as it could be a bad blower motor itself.



Customer: replied 4 years ago.

Ill try that next


Yes, the motor needs to be bench tested if you have in the vehicle 12v and good ground at 12vdc it should spin full speed/rpm if not then bench test... if the same then replace the blower motor which is most likely the problem.

If you need any further assistance just let me know.
