Default Cold in my 94 SSEI

I get only cold air when turning on the heat. Thermostat has already been changed. Coolant level is fine. Thinking there'* a control valve which may be bad but not sure how to get to it. Please help if you can!

Real Cold

I had this problem, my heater hoses cracked, causing coolant to leak...resulting in no heat in the car. But if there is no coolant leak then I'm not sure.

Maybe evap core...the blower motor is fine I take it?

I'll leave this one to the experts...have at it ladies and gentlemen

Welcome to the forum!

Are the hoses going to and from the heater core hot?

Also, run a diagnostic on your climate control to see if any codes are stored. (See tech-info)
