No heat 1993 olds cutlass supreme, we have put a new blower moter & new therm. stat and still blows out cold air. What can I do to get heat? Also fluid levels are fine.

If the heater hoses are getting hot, and the radiator is full of coolant, it could be a faulty blend door under the dash.

Check it the car has a cabin air filter... remove it vaccume out the air box carefuly and replace it. If you have a filter and you never replace it it is likly it is packed with what ever. are you sure the blower moter is working at all speeds? if not the blower motor resister is likly the cause. the resister is mounted on the blower box not sur on your car inside or out, if it is the problem then you should buy a harness kit too, because the ends ar most likly melted and not goning to be servicable.

first feel the heater core hoses see if both are hot if so then your problem is in the blend air door must be stuck on cold. is your blower motor blowing cold air if not your blower motor might be the problem. the blend air door is down by the blower motor.

If it is not blowing check your blower fuse first. If it is blowing cold air check your coolant level.

the heater control panel possibly bad. the panel where your heater is at. on the dash,actually where you're turning the directiona for floor and dash, or it could have a bad connection on switch behind the panel.have you spilled liquid on dash in the past? if so you may be able to pull the panel and clean it in order for it to work again. hope this helps!!!

your problem is with your resistor

I would advise you to check the wiring they could be causing some short circuits. That would be from the steering up to the wiper's motor.

Should be on the firewall under the hood or under the glove compartment. Depending on which engine you have in that car.

heater core is shot most of them are located under the dash board, look to make sure or call a garage they can tell u were its at
