Hi, I've got a '88 Sovereign. I've been having trouble with my puddle lights not working, my front interior and map lights not working either and the back of the seat lights don't work. I've got no power to all of them regardless if the switches are on or off. I've replaced all the realays and put new bulbs all around but still not working. The rear pillar lights work.
Can someone please help me 👍

 

Check connectors for corrosion at switches. Check power to switches and check and clean all grounds.

 

Yes I have done all that and still not working, also now the clock doesn't work.

 

Hi dom777,

Have you checked all the associated fuses? I believe all of those lights are controlled via the Central Microprocessor/CPU. Water damage to the CPU electrical connector or circuit board is a known issue, either because the duck bill drain in the windshield under-cowl (near the windshield wiper motor) has become clogged with leaves, or the A/C drains have become clogged with deteriorated foam insulation inside the Climate Control Unit (CCU).

Please keep us informed.
