So Its been getting colder and colder here, and I dont have heat. The blower works great but is only blowing cold air. just looking to get ideas of what to replace.

does your engine reach full operating temperature? (just under half way on the gauge)

If not, your thermostat may be stuck open.

Is your coolant full? If not, you have air in your cooling system. bleed the coolant/ radiator.

If it is not either of those, your heater core may be clogged or gunked up. It's not a fun job to replace one. (You'll be removing the dash & blower motor )

One more thing to check is that the lever for the cool/hot adjustment on the climate control is working. It connects to a cable which goes to a box on one of the hoses going into the center firewall in the engine bay. The box is only a couple inches. If it is rusted up, it may not be opening and letting hot coolant to the heater core.

Temp is good, and it has coolant. Ill check the lever and hope thats it. It is hard to move so maybe.

Thanks Man!
