Heat on blowing cold air only

Haven’t used my heat in six months. Now when I call for heat I only get cold air.
Any suggestions?

 

Not trying to be a smart ass, but do you still have the AC button on? Also, what is your temp knob set at?

 

Check the coolant level. The heater core is kinda the high point in the cooling system so if the coolant level drops a bit the heater core can get starved of hot coolant.

If the coolant level is full look for a blend door issue behind the dash

Grab both heater hoses going into the firewall and see if they're both hot

 

where do you live to need heat already? We could ship you some.

 

It could be an open thermostat. Or as someone suggested. Check heater hoses for temperature

 

Or an actuator door switch

 

Good point, if hoses are hot. Then likely clogged core. Or actuator

 

lol. My first thought too. We have plenty of heat even up here in the great white north.

Temp in the mid 80s and due points in the mid 70’s. It feels like Miami without the ocean breeze and the million dollar boats.

 

My truck is naturally hot

 

Sometimes I take my pants off and hang a leg out the window
