Question about 1996 Jeep Grand Cherokee
V8 , 4.7
P0202 means that there is a problem in the fuel injector circuit #2. You will need to measure the wiring from the injector to the PCM for continuity and the other side for 12V (with ignition in on. Be aware that the ASD relay (auto shutdown relay) will deenergize after some seconds when the engine is not started and you will loose the 12V. Since you only have one injector code, the 12V is most probably OK. I would swap injector #2 with an other (easy to reach) injector and see if the complaint will follow to the other cylinder. If it does, then the injector is bad and need to be changed. If it doesn't, then there is a good change that the driver in the PCM is bad and the PCM needs to be changed in that case.

I agree, these vehicles have a problem with the blend doors and since the accuators hit the door when it opens and closes, it breaks the doors. and it's a huge job to replace them.

P0700 means there is a transmission fault code in the transmission controller. Since the transmission controller doesn't have a light attached, it tells the engine controller to turn the light on using this code. You'll have to access the transmission controller to further diagnose the problem.

There are two parts to it, a voltage resistor, and the EL panel itself.
You need to remove the console first. There are 2 screws under the front rubber pad, two under the cup holder, two in the bin. Remove those six first, take the storage bin out, then slide the rear cupholder out, remove the two screws under the cup holder, and one in front of it.
There are a total of 6 flat screws, and 3 self tapping screws you have removed.
Put the parking brake on, shift the tranny to N, and the transfer case to the middle position if equipped.
Remove the entire console. Slide the shifter beezel as far up vertically as you can. There are 4 clips you ned to remove to do it.
You will see a blue and black wire running into the back. Follow those wires to the resistor. You will see a transparent EL panel attatched to the resistor by two clips.
Usually, one or both of these clips has come loose, causing the light to work intermittantly. Clip them back on, and turn on the headlights to confirm that the light works correctly now.
Re-install everything in the opposite order.

the squib is the explosive charge inside the drivers airbag. It is not serviceable and is part of the airbag, however, the squib circuit includes the clockspring and wire harness and they are serviceable.
Check out this website. The purpose of this website and company is to help peoplediagnose and repair airbag problems themselves without taking them to thedealer (if possible). It offers all thephotos and data you need to understand your airbag system, read the codes andreset the light.
