I found wiring diagrams at
http://www.dodge.com/bodybuilder/2004/docs/wd/rswd/tc.pdf
it is 2004 but use the wiring diagrams to test the wires
(most likely to fail where they flex)
because it is using logic gates disconnect the plug at each end of the wire you are testing or the damn thing will find a few diffrent ways to trick you.

Hook it up to a scanner and see what codes are in the system. Most part houses will check it at no charge but will not clear the code. Depending on what code is retrieved, depends on what you will do next. Some codes are soft codes that will not require immediate attention like small evap leak, while others will require immediate attention such as a p0302 which is a misfire on the number two engine cylinder.

could be a bad "ground", ground cable, or a short in a system.
Possibly the voltage regulator is not recharging the battery when the vehicle is running or even as simple as battery connections are dirty and loose.

The device that turns the radiator fan on is a temperature sensor on the lower radiator hose towards the engine block. That could be the switch that you are referring to. When the coolant reaches a certain temperature it tells the radiator to turn on. The relay then sends the power to the fan.

Looking at a wiring diagram an using a DVOM - digital volt ohm meter an testing the electrical circuits is the proper way to diagnose , not just replacing parts . If you do not know this ,your best bet , take it to a qualified repair shop. What engine ? 2.4 or 3.3 L .... Starter motor relay , PNP - park neutral position switch . B+ voltage at fuse # 9 40 amp. location - integrated power module .Just Replacing modules isn't the way , may need to be programmed -DEALER . Do you know what a starter relay is an how it works ?

Take the compressor relay out and give power from there.

Security light. The logic, of the computer, thought the car had been stolen. You did the correct thing, using the remote. Very well done. Now, to find out why the light was on. A lot of vehicles will sense a loss of electrical power and then the computer sees the power come back. This triggers the anti theft system to prevent a thief from starting the car. Using the remote, resets this. Now, have your battery cables cleaned. Obviously there is an issue when cranking the car, that is causing a low voltage issue. Hope this helps.

Sounds like that key has worn out or it's bend a little and not making any contact with the tumbler.

Do you know anything about electronic's ? Automotive electronic's take more of a beating , hitting bump's , pot holes ,curbs etc. Enough to jar even the best built electronic componets . Chrysler products have had solder joint's crack , causing intermittent connection problems , could be loose fitting electrical connection's etc.... There is a microprocessor with logic programmed into it , inside the instrument cluster , the gauges ,warning light's are all controlled by modules . The gauges get their info from the PCM/ECM - engine computer over what is called a serial data network , are you familiar with these . The PCI data bus is what it is called . NO Communication issues on 2003 Dodge 1500 trucks is best fixed using...

Probably the best thing to do would be to have the whole vehicle scanned for DTC'S - diagnostic trouble code's . Not at a part's store , they can not read codes in the instrument cluster , BCM - body control module etc.

You could probably check power an ground connections for the IPC , Looking at a wiring diagram so you know which wire's to check . Free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. year,make ,model an engine size . Under system click on body & accessories ,then under subsystem click instrumentation .Click search button ,then the blue link. To find ground location's on the vehicle you real need some kind of factory service info. or repair manual .

YOu should be able to tell if coolant leaks caused the coil pack to fail. I believe it is 2 issues.

You may have an issue with the directional signal switch in the steering column. Power to this goes thru that switch. It usually required removing the steering wheel to gain access to correct. You may not want to tackle this yourself unless you have a manual and the proper tools. I had to buy a special too to remove the gear selector to gain access. Only used it twice and had to get it from a Snap-On mobile truck salesman. What a pain!

Lots of possibilities from a bad solenoid pack to a broken gear or blown internal seal. No way you're gonna DIY your way out of this. Get it to a shop.
