The computer is trying to complete the command to turn on the ac and it cannot as it does not see a signal to ground.
The circuit has to be checked as to why there is no signal to the pcm

Thank you very much, the air and/or heat hasn't been coming out of the vents very well. And a year ago it was looked at by a mechanic who said it just needed cleaned out, but the problem restarted about 6 months later. Thank you again.

Would that relay cause the air or heat to not come out the vents very well? Or maybe it just needs recleaned again?
