Are you sure the dimmer control isnt turned all the way down?
Didnt think so, but,,,You know i had to ask :-)
These vehicles have 3 fuse panels.
Check the fuse in the passenger side fuse panel,,,see below.
Check this fuse,,,its what supplies ground to to complete the circuit.
Thats ok,,,,we are just working our way there,,,
I'm pretty sure the fault lies in the lamp dimmer module (see diagram i sent)
I dont have any more info where its at, other than behind left side of dash. If you can but another one, and then find it,,,i think it will solve this issue.
Do you have a DVOM to test every single component and wire in that circuit?
If not, we will just be chasing our tails by replacing parts,,,,not good.
I was refering to a volt/ohm meter, so you could test the resistance in the wiring,,,its a tough measurement.
Like i initially said, i believe the problem lies in the dimmer MODULE,,,not the SWITCH...did you by chance misunderstand me?
This is the only thing i have that tells where its located,,,,you probably are better off just getting the new one, then look under the left side of dash and match it up.
Maybe this will help....
Hi there, i have been thinking about this some more and now i'm thinking the park lamp relay might be at fault. if you look at this diagram, you will notice that the park lamp relay is what supplies the ground for the dimmer to complete the circuit.....now i'm nervous..
