Have no power at left headlight is it the TCM or likely the switch 2004 Dodge Dakota
NO DC power (like 12vdc ) you mean?
left low beans and high dead, and high flasher dead too? left.?????
no the TCM transmission brain does not connect to any head lamps
but BCM does. body brains.
yes all modern cars switch (electronic fuse) splits them
so if one shorts not going 80mph blind at night, (safety first) and all that. and the DOT laws that dictate that USA>
I will pretend you said USA, like I always do for the same reasons.
no country told
and then read the online service manual to you.
I will now answer for non DRL cars, no canada daylight running lamps malarkey.
USA no DRL options, that love to fail DRL does.
Not fog option,just heads./
yes, no fuses for one lamp
the central timer module run them directly,
this so called timer is BCM, the manual explains that.
things to do:
well test all lamp again LEft
low beam , high beam, and flash highs./
if all 3 fails ground wire is open
test all lamps inside and out to see if BCM fail in other ways
if only lows fail lamp is bad or wire to it is shorted to car battery
if only highs fail lamp is bad or wire shorted here.
if not shorted the wire is open
if you scan the PCM it will tell you Via BCM comms, the wire that is bad and why (open or shorted)
at the last resort.
reset the BCM by pulling its fuse (main) for 5minutes
fuse 12 and fuse 3 is BCM power.
or if brave pull battery neg lug for 5min. or more
and not all brains are reset, but be warned , relearn mode happens to transmission and shifts rough for 1hr or less and radio stations lost
memory of them only that you have set.
there is no fuse called RIGHT OR LEFT HL
