I have a 2007 Altima and the blower motor for the AC/Heat is acting up. It will not come on when the car is cold. once the car is warmed up and I have been driving for 5-10 minutes it will kick on and works fine. Any thoughts on why this might be happening?

Thanks,
Tom

I would definitely check the wiring connection directly at the blower motor.

nope i found the problem.. bad relay behind the fuse box. i switched the 1st relay(heater-blower) with the 2nd relay (radio) and it works fine now dont remember what thread i found that on but it definitely fixed the problem... now i just gotta go buy a relay for the radio.

Defrost Doesn't start until engine warm

I had the same problem, and it also meant the defrost would not start until the engine warmed up. Replaced relay as described in other posts - problem solved!
