Hello and welcome to justanswer.com
This problem is usually caused by a faulty lamp control module. There are internal relays and diodes that short out causing this. The module is located next to the trunk fuse box so check all those connectors to make sure they are tight and there are no signs of water leaking into them. We should first check all the fuses to the module and the body processor module. A blown fuse can also cause this as the module will draw power from another source. The fuses you need to check are #5 (10 amp) in the trunk, #5 (5 amp) in the left hand engine bay, #18 (5 amp) in the right hand engine bay, #6, #13, #14 all 10 amp in the right hand heelboard and #1, #8 and #17 all 10 amp in the left hand heelboard fuse box.
You are good! We are half way there... Very ironic, the very last fuse you suggested to check was bad - left handed heelboard #17. Once replaced, the reverse lights work!
Back to the other problems - mainly that the day/dusk lights do not come on (the switch does seem to work however as the dash lights do come on). Any thoughts?
Also, with regards XXXXX XXXXX rear blinkers - should they be the white bulbs flashing? or the red?
Thanks, XXXXX XXXXX release your payment.
Are you there???
I sent the payment but haven't heard back from you!
Please follow up.
There are no 'auto' lights in this car. On the left side of the dash is a single lever that pulls down.
Position #1 lights (or should) all the lights but not the headlights - including the interior dash and so forth. The dash/interior is coming on, but no exterior lights (lets call them 'running lights'. In the full on #2 position everything works fine. Any thoughts???
For the rear turn signals, the top outer bulbs do light (which is also the reverse light) it looks white, I guess this is normal then.
OK, so all fuses are double checked and working. ALL the lights work fine in the 'headlight on' position so the bulb connectors would have to be fine, right?
What doesn't work is the 'Day light' postion (however the dash dash and interior do come on, just nothing exterior - except the fog lights if they are activated). Would this be the lamp control module then?
