HVAC fan not working
After having my HVAC system serviced this summer, the fan in the system no longer appears to be working. I cannot get the fan to come on or change speeds at all despite manually fiddling with the HVAC controls. The blower motor is new as of last year, so it's not that.
Any ideas? Fuses all appear to be good.

Re: HVAC fan not working
Is this a manual HVAC or digital climate control system? Possibility of the blower moor control module or blower motor resistor. Even though the blower motor was new, have you bench tested it by applying 12 volts to the input pin just to make sure it did not fail.

Re: HVAC fan not working
It's a digital HVAC system.
Had it looked at yesterday. The wiring harness that attaches to the blower motor was corroded, which caused a short-circuit in the harness and blew out the blower. They replaced the blower motor and the harness and now everything is working fine.
