SOURCE: how do i replace heater blend doors on 1996 jeep

I haven't done one on a 96 before, but have on a 2000, while they are different body styles i assume they are very similar. On the 2000 it required removing the entire dashboard, center console and steering column. Evacuating the A/C system and draining the coolant. And finally removing and disassembling the HVAC box. While your in there take a good look at the heater core and Evaporator as they are somewhat common leak points in their corresponding systems. Won't want to put it all back together to find out a few months down the road that the evaporator is leaking.

Heater stuck full hot

Hello! The Blend Door Actuator (motor) is defective...The temperature/blend-air door motor is used on all models, whether equipped with manual or automatic temperature control. This motor is located under the heater-A/C housing directly over the floor panel transmission tunnel, and can be removed from the passenger compartment without instrument panel or heater-A/C housing removal...See diagram below...

When i turn on the heater it doesnt work but the AC cool works Whats wrong with heater?

Your Jeep has a common problem with what they call "Blend Doors", they mix hot and cold air to what the user put it on.

What you have is an "arm" that pulls on a peg to open and close a door, this peg snaps off over time and must be replaced in order for it to work again.

This issue has plagued WJ Jeeps and requires taking must of your dash area apart.

Yahoo, Google and or youtube "Jeep Grand Cherokee blend door repair".

I hope this helped.

2001 Jeep Grand Cherokee Limited..heating system doesn't work but ac does

You may have the blend doors problem which means the blend doors are in the closed position only allowing cold air. They need to be fixed. Google "heatertreater" to see full explanation and fix.

1999 Jeep Grand Cherokee the heat is not working or blowing?

2 problems?
No blower motor: Blower motor resistor very common or motor itself or heater controls.
No heat: Start simple with check antifreeze level after vehicle has sat for a few hours. If that's OK then it could be thermostat, heater controls, blend doors, water pump, restriction in cooling system

98 XJ cherokee sport 4.0 a/c blows hot air not warm, hot like the heater will not disengage. ac is charged lines and canister are cold. all positions on selector blows heater.

check that the heater control valve on the heater hoses is working, also check that blend door inside heater box and blend door vacuum motor are working. Likely the problem is with the door or motor, but unfortunately, the entire heater box needs to be removed to get to them on most vehicles.

No cold air just hot

System is vacuum controlled check for vacuum at the switch you replaced If it's there then check the blend door motor (moves the "flapper") If motor is good, then the door is stuck and heater box needs to be taken apart. If no vacuum at the switch, work your way back to the engine where vacuum originates to determine where line is broken or disconnected.

01 jeep grand cherokee heater works on driver side blows cold on passenger side

You have 2 posibilities.there are 2 motors on the heater box that run the blend doors for each side.That side motor may be bad or worst case the blend door arm that connects to the motor is broken.If it is broken the whole dash has to be removed so the heater box can be taken out to replace the blend doors.Big job,do a heater core while your there if you fix it so you dont have to do it again.
