Either the entire control panel has gone out or the door actuator motor has stuck or stopped working - real pain to change - behind the glovebox - has screws on top of actuator that are almost impossible without a swivel 1/4 wrench

I have a 98 bravada, when i turn on heat it blows cold air, the heater hoses don't even get warm they stay cold, what could cause this?


Low coolant level or the thermostat is stuck, have the engine operating temperature checked with a scanner

Problem with heating up and staying heated.


Thermostat is sticking or heater core is blocked.do not keep running it or it is going to ruin the engine. It is running hot regardless if is blowing cool or hot air. Do not keep using the car.

The heater blows hot air when in cool position on a 98 olds bravada


AC not working?

on a hot day it will blow warm/hot air if the AC is turned off or not working

If its hot air and AC is working then i would start by checking the fuse or relay. if its not the fuse/relay then i would look into the heater box there is a door that blocks the hot air

98 Ford Taurus Heat blows Full no matter how hot it is in the car and even though the Temp is turned down to 60. Also A/C does not work Blows Heat instead not just warm air actual heat. Can turn down fan...


The heater door is probably stuck in the full heat position. It could be a problem with the heater door motor or the controller - you'd have to check for both mechanical and electrical problems under the dashboard.

Still looking for a solution for my 98 Olds Bravada. Will only blow hot air. We've changed the blend door motor. Still only turns to the hot side. We've changed the Climate Control Head and the blend door...


Check your wiring with an ohm meter. Also ckeck the plugs at both ends and make sure there aren't any pins pushed out or bent. And just to throw this in, you may have bought a bad motor. You have other motors on the plenum, try swapping them to see if you get results. If they are accessible. Good luck

I have a 98 olds bravada. i have it on ac but hot


Does the AC come on and stay on? If so it will be either in the heater control head or a blend door or blend door motor!

98 Bravada blows hot air out all the time


check for a vacuum leak at the actuator under the hood

Heater temp on mercury '98 mountaineer only blows hot


Everything that is heat and cooling in a vehicle is controlled by vacuum from the engine. It appears to me that your blend door vacuum line to the temp control switch is either off or cracked/broken and not making things work the way you want/expect. It's the vacuum friend.
