ELECTRICAL PROBLEMS WITH TURN SIGNALS,EMERGENCY FLASHERS,PARKING LIGHTS
this car have DRL? day light running lamps?>? option
or manditory in canada. do tell !
so the fuses blew again, and you didnt look?
id fix either park/ hazzards.first
both work with key in pockets for EMERANGACY uses, even
when 100 miles from car, keys in pocket, by DESIGN. (all cars)
so due to that fact its a very simple system.
but in 2007, they makers do all they can to make it more complex
than ever necessary, (saves money with copper)
the 2 features are hot all the time, that means they wire to the
battery directly with ONLY a fuse, to stop fires.
so id bet it blew the fuse (got trailer wiring hacks in back>?) collision damage not fixed right>?
do you have the factory trailer option?????
park seems best., easier
it has 2 fuses to the rear.
the PARK relay closes, and powers the fuse and then lamps.
so both cant blow. left and right are Fuse 7 and 9
the BCM , (body brain puter) energizes the park relay
so seems its not.
my guess is the BCM has lost power.
in the dealer they can scan for BCM errors. and say fast what is wrong.
the list for PARK dead.
1. Ineffective or missing relay.
1. Test and replace park lamp relay if required.
2. Ineffective control circuit.
2. Test and repair open park lamp relay control circuit if required.
3. Ineffective switch.
3. Test and replace multi-function switch if required.
4. Ineffective BCM inputs or outputs.
4. Use a diagnostic scan tool to test the BCM inputs and outputs. Refer to the appropriate diagnostic information.
here is my list
all park lamps burned out, (no way) but had it happen in 1980.....ask how? (alternator went nuts to 30v)
relay park missing or bad. (pray)
the park switch( in combo-mult- section switch is bad) nah.
The combo failed to tell BCM of this state change (comm fails)
the BCM failed to hear the command.
the BCM is bad or lost power (fuses)
the BCM failed to close the park relay.
the BCM has 3 power fuses. fues 34 is hot all time, id bet that fuse
allows the BCM to turn on parks, at any time.
others are key power, fuse 22, and 13. to BCM
the back unlocks doors, and does so via FOBs. car locked and parked and no key in ignition, so again, fuse 34 rears ugly head
i hang hat on 34, but got tired, if reading 50 pages of power distrabution and comms.
it is very complex car, and one of the first cars to do this....
