Question about 1996 Jeep Grand Cherokee

Need help on how to remove a 1996 Grand Cherokee HVAC box

I need to know how to remove a 1996 Grand Cherokee HVAC box. I need to replace the evaporator and heater core in a 1996 Jeep Grand Cherokee Limited. I have the Hayes manual but there seems to be alot of items not shown for my year although the manual states that it covers 96-98 Grand Cherokee. So far I have been able to remove the dash, air bag and instrument cluster except for the speedometer, does this have to be removed along with the steering wheel and also how to remove the air ducts as I cannot find any way to remove them, it's a very tight fit and I cannot find any other screws to remove.I have removed the nuts on the firewall side and I am about to remove the heater hoses and the AC lines. The rad has been drained and the R134A coolant was exhausted when the AC line was broken at the firewall and NO I did not break the line, I took it to a shop last summer before a trip to New Brunswick and they said everything was fine until I turned the AC on in Quebec - it lasted for all of 5 minutes !!! so now I have to replace the AC parts and the job priced out at over $1500.00 - 2300.00
Any help would be appreciated.
Thanks
Dave W.

Rhe entire dash in one piece has to be removed.the steering column has to be removed [dash comes out in one piece guages and all] when your done all you should be able to see is the sheet metal fire wall and the heater/a/c box. it takes a chysler tech about 6 to 8 hours to do one of those. and the reason we can do it that fast is because those were always leaking and we have done scores of them. point is dont get dicouraged its going to take you a long time

I have a 1999 jeep grand cherokee and the heater is hot on the drive side and cold on the other side


Assuming you are going to replace the 99/04 Jeep Grand Cherokee blend doors yourself.
You would start by disconnecting the negative battery cable.
If you are going to remove the dashboard, etc to replace the blend doors.
some websites give you complete instructions with plenty of pictures.
It will take the average person with little or no auto repair skills approximately 12 to 16 hrs.
The vehicle will have to be taken to a shop that can recover the refrigerant before you start removing the dashboard and HVAC box..

If you are going to do the type of repair where you cut an access hole in the side of the HVAC box.

A short version of how the access hole repair is done.

Disconnect the Negative battery cable.

Lower the glove box

Remove the actuator motor - You will need a Phillips screw driver

Cut an access hole in the plastic HVAC box - Use a multi-purpose cutting bit, you will need a rotary type of cutting tool, like a Dremel, RotoZip, etc. Or you could do the cutting by hand with any type of small cutting tool, it will just take longer doing it by hand. Or some people have used a narrow pointed soldering iron!

Remove the broken blend doors

Install the new blend doors.

Replace the actuator motor.

Close the access hole - Replace the wall piece of plastic you cutout -Use foam tape or an aluminum tape to cover the groove made by cutting the wall.

Close the glove box.

It is almost as easy as what you just read, the hardest and the most time consuming thing to do is cut the access hole.
The job should take between 30 minutes to 1 ½ hours. Depending on how long it takes you to gather your tools, etc.

Afternnon, just wondering about the best way to locate the blend doors in the hvac box without ripping out the dash on my 2000 jeep grand cherokee. Thanks in advance. Duane


y9ou can gain access to the driver side blend door actuator by removing the glove box. The actuator will be in the left corner of the glove box opening. If you remove the actuator you will be able to turn the pin. If you can turn it 360 degrees the blend door is broke.

If your lucky its only the drivers side. If you get the repair kit from chrysler it will come with instructions with pictures on how to replace the blend door without pulling the HVAC unit/Dash. If the passenger side is broken the HVAC unit will need to be removed.

Heater treater (google them) also have a metal blend door replacement and instructions online on how to replace them without pulling the HVAC housing.

I need help with heater core replacement for my 1999 jeep grand cherokee laredo


Changing the heater core requires complete removal of the dash panel and plenum box. To do this you have to remove the steering wheel, steering column, evacuate and recharge the refrigerant system and drain the radiator. I would only consider changing the heater core if it is physically leaking into the passenger compartment. If the problem is heat transfer to the HVAC system only, the problem is more likely with the blend doors. Check heatertreater.net for pictures and diagnostic information.

Entire heater needs to be replaced


i work at a dealer and generally its is 8 hours labor to remove the dash. disassemble the HVAC box, repair whatever doors or motors broke, checking the Evaporator and heater core for leaks. and it typically comes out to around $1400 when all is said and done but thats also at $90 per hour
