The problem is when i turn on the vehicle, its fine. 30 secs after starting, the sentry key light comes on and stays on but the vehicle stays running. the light use to go out sometimes then come back on but now it just stays on. then, whenever it feels like it, no set amount of time, the gauges will start to flucuate, shut off, come back on, along with any indicator lights on the panel. they shut off, come on, shut off, etc..... without any regular sequence. sometimes, all gauges will quit and all lights will come on but the engine stays running. also, the key fobs no longer open the doors and the driver door module doesnt function properly when jeep is running but works fine when engine is off. when its running, you can sometimes hear the module click and the locks will either work or not work until it clicks again. the codes are p1686 and p1687. there are numerous modules i've found that could cause this but i need more accurate diagnostics as i cant afford to guess. i've already replaced the driver door module that one garage claimed it was. it still clicked and the light still came on. i've had it on a scan tool and they couldnt narrow it down. is there a way i could dissconnect the skim altogether??? i dont want it if its going to cause problems. the problems with all these crappy computerized vehicles really makes me miss my old 75 malibu!!!  

yikes looks more like you have a lemon. that's a first that i've heard of i think you were better of with the malibu unless you want to go to a dealership and spend alot of money on the car i'd get another car  

I have read that if you cut the yellow wire on the SKIM while the car is running that it will disable the SKIMM in the bypass position.  I had research the SKIMM device because I had wonder if my car was shutting off while driving was cause by it.  In my case when this happens ... the gauges are off and the car is disable until the gauges come back on in about 10 minutes.  From what I have read the SKIMM device is designed not to cause a car to die when running only within a few seconds of starting.
