It has just began to get cold enough to use my heat up here in Minnesota. When i went to use my heat today i could not get air to come out of my vents the 2 lights on top of the REC and A/C switches blinked and i could not get any air to come out. What could possibly be the problem now?

 

Blinking lights mean that there is a code thrown indicating a possible problem. You can pull the codes yourself on the B side of the diagnostic box.

 

If the blower motor doesn't come on them most likely the motor is bad and causes the lights to flash.

But yes pull codes.
