SOURCE: 1998 buick park avenue drivers side blows cold, passenger side hot

sounds like the drivers temp door actuator is not working should be located on the drivers side of the air box down by the gas pedal or center dash area.

SOURCE: cold air on passenger side warm air on drivers side

Actuator motors either get a tear in the rubber or a hose is broken and not letting vacuum assist in its opening.
You can try moving the lever by hand and see if the air gets colder on the bad side.c976077.jpg

SOURCE: How do you fix the driver side air blend door actuator?

you cannot repair the actuator you need to replace it with new one. These motors turn but get weak with time. if you test it, it works, put it in and it doesn't. this is because the motor is weak, unfortunately GM does not sell these motors separately.

SOURCE: 2001 aurora drivers side vent

Yes, The driver side actuator has failed, actuator is mounted on passenger side of heater case under the dash, remove close out panel on bottom of dash, remove glove box then turn on key actuate the temp control switches and watch for movement of door linkage and you can tell which actuator isn't moving.

Side windows on passenger side fog up. Not on driver's side, only on passenger.

so find out which vent is dead,?
before 5 gallon LYSOL flush an a week long GAG !
make sure first never to use RECRIC, when wanting to defog.
and is the A/C running in dash defrost mode (compressor main shaft spins)

if a vent is dead, its a bad damper valve, (not saying a part, a function)
the book is free, you can read it, HVAC. see venting and dampers.
its very simple in concept, a fan, a damper and dry air. hot.
the heater core makes heat the non recirc, damage gives you fresh air, the A/C makes that air dry. and the dampers the supply all vents work work.
so make sure the controls are set right,
then see if the upper vents all blow, with hand waved on them.
see? that is easy, and not reporting a dead vent ,makes help harder.
the FSM is on line, ill look for you.
but first HVAC 101
  1. does blower work on high?
  2. does the recirc turn to fresh are,and you get fresh air with blower off moving, at all top vents. y/n
  3. do you have full heat? 180F + engine heat (scan tool shows this as ECT)
  4. do all vents top work , blower on?
  5. is the A/C compressor working in A/c mode (cold) and Defrost?
  6. more... below.
Rule one, dont work in dash until air bags are DEFEATED (injury) (pull battery neg lug, and wait 1hour)

got fsm page open, ill state some facts needed to fix this.

first ill prove the dash system does not need total dismantle
for all jobs. Does NOT.
Air /mix blend door
Single Zone/Dual Zone Driver's Side(FSM)
  1. Disconnect and isolate the negative battery cable.
  2. Remove the instrument panel silencer from the driver side of the instrument panel.
  3. Remove the three screws that secure the blend door actuator to the driver side of the HVAC air distribution housing .
  4. Remove the blend door actuator from the air distribution housing and disconnect the HVAC wire harness connector from the actuator.
  5. Remove the blend door actuator from the vehicle.

next page, is blend door 2, type.
has vacuum servos.
we move the controls and make sure all servo vacuum motors

this car has driver side and passenger side seperate blend doors.
so,,, we are getting close here>
if the defroster fails,(seems not) then that is electric motor drive
and very hard to test . (if not door jam)

in any case, we need to know what part is failing,
if the passenger blend is dead.
seen below,
we then must find out why
1: just stuck.
2: servo actuator failure
3: controls to #2 above bad, or connections to each.

login to see HVAC chapter, read how it works and the tests.

My heat works only on passenger side and is not very hot at all. But the other day the vent on drivers side near the window worked just for that day...sometimes the heat on passengers side is extreme

I would talk to a dealer or two.
You could have a damaged heater box or blend door. The blend doors direct air thru the heater core and the vents.
There was a recall for some blend doors on some Jeep models.
You may have to contact factory customer service to get it fixed.

Driver side blowing hot air passenger side blowing cold air

I'm having the same problem except on mine it's the driver's side that's blowing cold. Do you have the pictures in a finer resolution? I can't make them out and when I zoom, they are too grainy. Does the replacement require removing the dashboard? What's the general cost of the acuators? Are they readily available at like NAPA or other parts stores?

I have a 98 ply grand voyager, and have heat from the drivers side vents, but cold air from the passenger side vents? please help

Does your van have seperate controls for driver and passenger temperature settings? If so the most likely cause is a broken actuator or broken passenger blend door. Unfortunately, the only way to repair a broken blend door is to remove the dash and the HVAC assembly.

How to replace a Blend Door Actuator on a 2000 Dodge Ram 2500 Conversion Ram Van? The air blows out the top, but will not blow out the vents.

Blend door mixes hot and cold, not a distribution control. Look for loose or dislodged vac lines... Heater designed to fail in defrost mode.

Dual AC not cooling on driver's side. Is there a fuse for this?

There are two blend doors with actuators in models with separate controls for driver and passenger in the HVAC unit. Apparently the driver's blend door is broken/jammed, or the actuator is not working. You'd need to check a service manual to determine how hard it is to get to and repair the driver's blend door.

1999 cadillac Deville cold air blowing out passenger side vents

Sounds like a Blend door issue, but could be the controller switch, Test ALL modes of operation to see what works and what does not. That should narrow it down a bit. The Blend doors are flap/ doors that regulate air flow, newer vehicles are plastic - electric assemblies ...prone to failure. Any clicking or thumping noises during switching modes and on-off suggest a bad Blend door. Hope that helps...good luck
