blower relay buzzing + no HVAC function
Turned on my 2005 F-150 XLT Crew 4x4 5.4L V8 today and the ac I left on the night before wasn't working. No response from the controls, and there was a buzzing sound with the ignition on. Checked the fuses & relays and sure enough it was the blower relay buzzing.
I assume I just need to replace the relay, but with all the threads of the Blower Fan Controllers going bad (blower only working on one speed vs. all, etc.) does this sound like something more than a bad relay? Is there a way to test it?
Thx,
