Hello friends!

My 2003 bird has no light in the instrument cluster or shift indicator (makes night time driving a bit strange), and I was thinking its the FEM as I've seen on here, but I scanned for DTCs and it came back with several DTCs for circuit failures: Fuel Sender Circuit, Turn signal/hazard switch signal circuit, Headlamp input circuit, etc. Here's a screenshot from the scanner app.
Some of the DTCs say they're from the Rear module! I'd love some input!

Do you think its the FEM or something in my wiring/fuse boxes?
I replaced all of the FEM and cluster related fuses after the lights went out the first time.

Many thanks in advance!IMG-2667.PNGIMG-2668.PNG

If the only problems you are having are with instrument cluster and shift indicator lighting, than your FEM is most likely the cause. As far as the B and U codes that your Veepeak OBDCheck scanner detected, I think those codes were stored when you replaced all of the FEM and cluster related fuses. Are you able to clear those codes with your scanner, and if so do they return?

I sent my Fem to module masters. They sent it back stating all the components they repair worked. Credit to them for not charging me. I have tried everything and can not find why I still do not have dash lights or shift indicator lights. Can someone explain the procedure for testing Fem to see if it is the Fem. Or send me repair manual for testing Fem.
Thanks.

Sounds like you just had it tested by module masters.You don't have dimmer switch off do you?

Yes, I cleared them once before, but then I believe I checked the fuses again. 😅 So, I will clear them and see if they return and leave those fuses alone in the meantime. Thanks!

New symptom this weekend:
The Odometer displayed "Lamp Out" or something similar and my right turn signal indicator flashed faster, as if a bulb were out. BUT, the message was gone by the time I parked and the turn signal functioned perfectly once again..

That's not good to hear! I feel your pain! I think I'll be sending my FEM out to Automotivemodules.com for $190 with my fingers crossed. Its really strange driving at night with no lights in the Instrument Cluster!
Have you thought about sending your FEM to another specialist?

Yes I actually just purchased the repair manual to see if I can determine it is the Fem. Dash lights and shift indicator lights out seem to indicate the Fem. I May gamble and send it out some where else.

They where actually pretty east except for the contortions with your body to reach in and disconnect them.
The contortions are killing me! I think I'll be removing the lower finish panel for more access, this evening.

This picture from the instructions I've found in the forums was throwing me for a loop, but I think its just behind that finish panel!
Correct me if I'm wrong, of course!
