Mind-boggling electrical issue
Okay, 2006 dodge ram quad cab 1500 with 5.7
Several electrical issues which MUST all tie together somehow.
No headlight on left side on dim
No heat or power control on side mirror on left side
No speedometer, odometer, and (of course) no cruise, accel, or resume
Did replace speed sensor on rear end housing w/ no change
REALLY need the speedometer and headlight resolved, everything else would just be icing!
Have been a heavy equipment mechanic for 14 yrs so I am mechanically inclined but unfamiliar with auto mechanicing. I do know with certainty that all fuses AND relays are good. All bulbs are good. Please help I'm losing my mind!

I hate to say it, but it sounds like one of two problems, or a combination of the two. I'm assuming you have swapped bulbs between the two headlights to confirm it's the circuit and not bulbs, gotta ask, there are some silly people named brad that don't do that sort of thing. Your most likely issue is your TIPCM which controls ALL of your vehicle's electronics and if you have a bad module then you will have these same symptoms. One other potential, but equally likely, issue is a bad gauge cluster which would need to be completely replaced. Your TIPCM could have gone bad and taken the cluster out, these things do happen, I fried my passenger side circuit and I also had a demonically possessed tach and voltage gauge.

One of the few upsides to having a pre-06 3rd gen.
