Heater blowing cold.
 

I bought a cherry '95 (66k miles, the drivers chair feels the same as the other 3 captains chairs) G20 this Summer, decked out mighty nice. Auto reverse cassette, TV, VHS, 4 way ambient lighting, 4 captains chairs, massage seats, reclining bench/ bed in the back, etc.

To the point: Now that the Midwest Autumn has arrived, I notice that the heater blows cool air. Sustainable for now, but unacceptable come winter.

Any sage advice out there on this one?

Peace!

Several things here. What is the coolent temp at operating temp? Does it blow air out all vents or just defrost, or just in one outlet, i.e. floor vents? Is the heater hoses warm/hot when at temp? Need these inpute to continue.

Thanks for the response Kevinkpk. Might take another day or so before I can get these answered (not the daily driver).

I'll let you know.

I figured it out. The heat blows when I have it set on vent. So I guess there are some input hoses transposed.

I have a 2015 Chevrolet camaro convertible, a body shop put a new bumper on the car, then i noticed my heater was blowing cool air. Found out there is a rear compartment fuse box with the fuse F28 that is the Air Condition/Heater Ventilation fuse, wondering if they disconnected that fuse box some way, or the fuse is blown after the rear bumper installation, the gut who installed the new bumper says its my thermostat stuck open

99 chevy tahoe LS I'm not getting heat when heat is off the temp will get to like 150 once I turn on the heat the temp gauge goes down to like 120-130 nothing but cold air...i changed thermostat already but nothing changed..help please!?

make sure there is enough coolant and you get rid of trapped air.

Also, try the Tahoe section.
No idea why people are posting random vehicles in the Van section.

I discovered recently that many late model vehicles have a door that opens and closes when you turn the temp knob on the dash board. The opening and closing is what dictates the temp of the air coming out the inside vents. A mechanic informed me that many vehicles have had issues with the door not closing entirely thus allowing cold air in the heater compartment which reduces the temp of the hot air that is suppose to come into the vehicle. You would have to remove the cover from the compartment that houses the small radiater that is suppose to supply hot air to the inside of the vehicle and operate the temp control knob to determine if the door is closing completely and tightly.
