A few days ago, my A/C wouldn't kick on. No motorz, no air...not even outside temp air. A few days after that, everything is back to working just fine on all temps and speeds. Is this a sign of the impending doom of my blower motor, or maybe something else?

 

It may be a resistor or connector with a poor connection. What is your vehicle?

 

Or bad/failing ignition switch....

 

It's a 97 Cherokee SE, 5-speed

 

Check for voltage at the connector in the different positions & settings. Report your findings and work backwards thru the controls to the battery.

 

Will do, thanks for the advice!

 

I ran into a similar problem last year with my 2000. Through trial and error and troubleshooting I eventually ended up changing the blower motor and the problem has never come back.
