Electrical issue ( no start )

[sportsman70003]

Working on a 2003 Dodge 1500 that has some kinda electrical issue. The truck has been worked on by 2 or 3 others pervious to me. The little red dot on the right side of the instrument panel is blinking and when you turn on the ignition switch on with the key the instrument panel does not come on. The radio makes a noise but does not come on either. Here are some weird things I've found. All the windows roll up and down with the ignition switch off. Also if you have the windshield wipers on and push in on the key with the switch off the windshield wiper come on. I'm leaning toward maybe a bad ignition switch but want to ask you guys first if anyone has seen this problem or if mabe there is a test I can perform on the ignition switch.

OK after further inspection the SENTRY KEY IMMOBILIZER MODULE has been removed by someone that was previously working on the truck. A little history that I have found out about the truck is about 18 months prior to the truck not starting the whole steering column and instrument cluster was changed due to a wreak. Everything worked perfect till one day it did not power up the instrument cluster and just had a red blinking light. The truck has been to a couple garages and a dodge dealer with no luck in fixing it. Not sure who took off the SENTRY KEY IMMOBILIZER MODULE or where it it now as its not in the truck. It has the black ignition key. I'm guessing I'll have to buy another key and have the SENTRY KEY IMMOBILIZER MODULE reprogrammed? Still then i don't know if that will fix the problem.

Got do digging around and looks like I have don't have 12v on fuse number 28. Thats the fuse for the instrument panel I think. Anyone have a diagram so I can check why i'm not getting 12v to number 28 fuse?

Get yourself a back probe kit, they work great at finding faults.

Ok got the instrument cluster and everything working. Problem is now a soon as I turn the ignition switch on and try to start the truck the alarm goes off. Is this because I dont have a SENTRY KEY IMMOBILIZER MODULE? Not sure if they tried to bypass it and removed the module or thought the module may have been bad and just never got around to replacing it. Is there a way to bypass the alarm?

Ok got a question before I send of my PCM to get it flashed. I have a code P0633 skim key not programmed in PCM. Is there any way to run the vin and check to see if this truck came with the skim? It has the black dodge key and it don't have the skim module (unless removed by the previous shops that have worked on it). I talked to the guy at Auto Computer performance and he said for $175 he could take the security out of the PCM.

Sounds like the issue I'm having, 04 1500 4.7L. It's happened twice now, go to start truck and everything dies when I turn on ignition switch, all that is on is the red dot on the dash kind of dim but steady not flashing and a ve3ry weak buzzing kind of noise. First time I replaced the ignition switch but that wasn't the fix but I left the new switch in anyway. Ultimately I just kept removing the negative post, let it sit for a while, put battery on charger, ****** around w/steering wheel, moved up and down with tilt kind of banging it around, after several tries of hooking up the battery on and off it all of a sudden worked. That was about two weeks ago. This afternoon it happened again, went to start the truck and same symptom, turned on ignition switch and everything went dead except red dot on dash and weak buzzing. Immediately removed negative battery post and let it sit for half hour or so. put negative post back on, lights came on when I opened door, turn ignition switch to on dash lights and stereo come on, looks good, go to start and all seems to short out and goes dead, red light on dim and low buzzing. left it for night with negative battery post off, and just charged battery. When the problem first happened as best as I can remember both times the drivers door was open, not sure if that's related to issue or not. I'm at a loss as to what could be the culprit since the ignition switch is new and didn't effect the issue. I'm curious to hear more about what you find out.
