Well.... I checked the fuse and it was fine like I said, but what I did find out was it does NOT show any voltage at the pins, UNLESS you put the positive on the one pin and the NEG on the battery ground (on the battery). Touching the two pins with + and - no voltage, now that is weird. Sooooo, I found out the solid blue wire going to the resister and fan motor has no voltage when the ignition is on or off for sure. So what I had to do was run a wire from the battery positive nut on the fuse block around and tape into the blower motor. It works this way, problem is.....you can turn the fan on without the key turned on, so if I or someone forgets......dead batteries. I will have to see where I can get 40A safely from the fuse block so it only turns on when I turn the key on. Any other suggestions welcome. Cheers

So......I took the fuse block out and it has NO corrosion underneath, ultra clean. Turned on ignition and there is NO voltage between the two points the fuse attaches too. hmmmm

Moparman I read over your message and am a tad confused. Are you telling someone something about this or asking? My 03 had a dead pedal and I changed the apps sensor and did NOT have to change the setting and if fixed the problem.

Ok sounds good. I have a Red Neck fix right now....battery in back seat, wires and a switch to battery till I figure it out.. haha Wish I could find a service manual for my 2012 online somewhere.

No power to fan when tested with meter. That's obviously when ignition is on and fan dial to max. I checked the fuse and it appears to be fine. I want to find a schematic to see where everything goes and if there is anything else in the line from motor back.

Now that makes more sense.

Hello Anyone have any issues with the heater fan inside the cab not working? Mine died. I replaced the resister/relay under the glove box and it still doesn't work. I also took the blower motor out and attached 12v and it spins great. The fuse also looks good. Help?

Here we go again..haha Now that the 2012's have been out for a few years, anyone have any tech tips, tricks and or ideas to help with fuel mileage etc. Obviously no keep your foot off the pedal and so on and so forth.

Good tip.

Found my old list of codes today incase you don't have one. Well not mine but a list I got online awhile ago. Here is an "almost" complete list of 3rd Gen codes. Every year, as DC migrates more hardware to software, they invent new codes for those systems. This is what I have for my 2003. There are a few new ones for the 04.5 and up trucks that I can’t find right now. If anyone has the new additions, feel free to add. There are two categories, P-Codes and C-Codes. P-Codes are engine related. C-Codes are support system related, as in your instrument cluster. When checking codes, "P" codes are self explanatory as it will show up with a "P" at the beginning. C-Codes will just give you two sets of numbers with a space in the middle, like "01 00". The first set of numbers is the code. The second set is the number of engine restarts that have taken place since the code was set. Gives you a good indication of how long ago it was.

I think the 03's have a lot of connector issues. I just checked mine and found 9 codes..haha

Moparman, it seems things have become very quiet in here. Any thoughts on a ATS atomizer?

Hope it all works out. let us know how you make out.
