Question about 1998 Oldsmobile Bravada

1 Answer

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 motor STILL only blows to the hot side. It was suggested that the "programmer" may be the problem. We pulled more of the dash out to get to it, unhooked the programmer and the blend door STILL turns only to the hot side. We've tried pulling the fuse to the radio to reset the computer with still the same result. We cannot get the new blend door motor to turn to the cold side. Any other suggestions??

    Thanks for everyone's assistance. After it was all said and done, the new blend door actuator motor was bad too, there were some damaged pin connectors on the wire plugging in to the motor and the vacuum control solenoid was bad. 3 problems fixed and now my climate control works like new!

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

Air conditioning system, when you turn on the air conditioner the drivers side blows cold air and the passengers side blows hot air? What causes this problem?


The most common cause of this is that you have a stuck air temperature control blend door, this can be a motor actuator issue or a jammed door or both (common). To replace both parts you will need to completely remove the dash from the car to access the blend door.

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

How come when i turn heat on. driverside blows hot but passenger side blows cold


talking from experience there can be 2 problems , either the "blend motor" on the driverside of the air register has failed or the door inside the register broke i would say 9 out of 10 the "blend motor" is the problem , on a scale of 1-10 its about an 8 to change the dealer refers to this part as a blend door actuator

Where is the driver side blend door actuator on a 98 Seville STS?


I believe that the right side has a blend door actuator, and the left side or driver side just gets air from the regular flow from the programmer and vacuum motors.

My 98 olds bravada started blowing hot air even when the air and heat is turned off .....my heat and air both dont work now ..... any solutions?


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

My heater only blows out cold air. When I first turn it on it blows out hot air for about 3 seconds then it turns to cold air. I have flushed the system twice, and that didn't work so I changed the...


check the vacuum lines going to the h-vac (under the dash where the blower motor is) make sure there are no vacuum leaks if there are no leaks start checking the blend door acuators firts locate all of them then start looking for the one that closes and opens the cold and hot blend door. turn the nob to heat and the other one to panel (not a/c panel just air) then if your not sure which one controls the hot and cold blend door start checking to see which acuator has vucuum going to them if there is vucmuum going to them but the acuator does not move replace it.but if it does compress take the rod lose from the blend door and see if the door in side the box is broken. if is not replace the climate controler on the dash. i hope this helps.

The driver side blower blows hot air, but the passenger side blows cold air.


common problem, you have a bad blend door motor, also be careful sometimes the blend door breaks at the end that goes into blend motor if is then blend door has to be replaced also w/motor hope this helps, ive done a lot of these, good luck.

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!
