Hello all,

I have an odd situation going on with very cold days, say below 15 degrees or so. The blower motor for my heat/AC does not come on. I push the temp controls and what not but I get no air movement. The heater core heats up and while driving I get some heat due to air coming in through the various vents. Sometimes the blower cycles on and off and when this happens the recirc. button comes on and stays on as well. When the temp. is warmer I have no problems what so ever except in the summer when the AC kicks on and off but does not affect the blower. Any advice or maybe just info on what is actually happening will be greatly appreciated.
