Also, my speedometer hasn't worked in God knows how long, and I've replaced the VSS, and it still doesn't work. When the speedometer doesn't work, then neither does the odometer and the speed control. The tachometer works just fine, it's just the speedometer that don't work......any ideas ????? I need help....... Thank You
My second issue is that my passenger side vents are shooting out cool air when the heat is on, and warm air when the air is on. From what I've been reading on here this could have something to do with the blend door for the passenger side, and I think I remember reading that this is more difficult to fix on the passenger side than for the one on the drivers side. I am fairly mechanically inclined, more with hammers and nails, and want to know if this is as simple of a fix as some of you are saying.
Lastly, I'm reading about fault codes on here, where do you find those at? Do I need to take it to a garage for a diagnostic to get the fault codes?
I have a 97' and recently, the A/C died. Today, out of nowhere, the blower went. I checked every fuse (both inside and near the engine). All of the fuses are perfect. This does seem to be an electrical issue, but does anyone have any knowledge as to where to start with this?? It will be 91 degrees here in PA on Friday, and I am freaking out!! Please HELP!!!

Thanks
Your symptoms sound like the common blend door problem.
First thing is you should check the HVAC system fault codes.
The cost can range from a DIY job of $20 to a repair shop cost of $1,800
Of course the cost depends on what is wrong with the system.
Also if you cut an access hole to check the blend doors and rear actuator motor (The actuator motor between the firewall and the HVAC box)
And you find that the rear actuator motor is not working.
That does not mean the actuator motor is bad.
Usually what happens is the computer will shutoff an actuator motor that makes one revolution without any resistance.
That actuator motor could still be in good working condition.
Post a message, if you need more information and on how to check the rear actuator motor.
One more thing....I took my 01 GC to the dealer to get service, they checked off the "checked battery and cables" I came home and was looking under the hood and the battery cable came off in my hand, I went to the dealer and yelled, even went and found the owner and they both said they just look to see if battery is there and not covered with corrosion....they did not touch the battery or the cable ! No checking of water or to see if it was secure or anything...they just look to see if its there !!!! I guess they did check the tire pressure as all 4 air valve dust caps are missing ! Never take the dealer shops or any shops word on what they did...check everything yourself ! Love my Jeep GC but hate the dealers and their shops !
Does anybody have experience with this repair.
It looks like the heater core is leaking. The procedure in the shop manual indicates A/C evaporator core and heater core must be removed as an assembly. Not very efficient if the problem is just the core.

Thanks in advance
