my best guess would be the heater valve.

 

maybe you are somewhat confused and turning your air conditioner on? Instead of your heater? Hey man it could happen, I get confused too

 

Maybe the cable that connects the control to the heater valve is broken. If you're lucky it's just disconnected.

 

This could be...to check the valve for your heater is below the glove box to the left. Have someone slide the lever on the HVAC controls from hot to cold to see if it moves.

 

what's your coolant gauge indicating?

 

easist: top up fluid. especially coolant

 

Mine has 2 cables. First one goes from the control slider down to the bottom of the console, passenger side, near the floor. It pushes a lever that works an air damper. The other cable goes from there thru the firewall to the heater valve. The heater valve is on the heater hose, against the firewall, kinda under the fuel filter.

Have someone work the slider control, while you watch for the cable to move at both of those places.

Air bubbles in the heater core can make it blow cold. You gotta find out whether that's your problem, or the cable.
