Yes, a faulty blower motor relay can cause the AC to blow hot air. If the relay fails to supply power to the blower motor, the air conditioning system may not function properly, preventing cool air from being circulated. Additionally, if the relay affects the compressor operation, it could lead to insufficient cooling. Therefore, checking the blower motor relay is essential when diagnosing AC issues.

If when changing a blower motor on an 1988 Ford F150 the blower still does not blow and the fuse has been changed what could be the problem?
Check the blower motor resistor/relay pack usually under the hood connected to the blower motor. You can start by using a multimeter and see if you are getting voltage to the blower motor electrical connector. It should read between 12 and 15v. If not then most likely the resistor/relay need to be replaced.
