Thanx for the advice on the fuel pump relay. Replaced it today and it fixed it. Cost: $140 and and afternoon from work. While at the dealership, I looked at the electrical shematics and discovered that the fuse box has a headlight module that most likely is the reason my high beams don't work. (mentioned this before but still a problem). Only problem is the dealership want $230 for the Module. Any ideas on where I might find it a little cheaper?

Much more common for both bulbs to burn out than for lamp monitor ECU to fail!! Do you have power to fuses(1 for each hi beam)??

New bulbs, new fuses. Only other thing I havn't checked are the switches on the column and the dash. Switches work fine for every thing but the high beams. And the hi beam indicator light is also out (makes me think proble is not in either switch). I think it's the module because the "lights out" signal on the dash flickers like it has a short at times. Checked all bulbs and they are ok.

Checked fuses holders with continuity light. Low beams, ok. Hi beams fuse holders have very low current on the bottom terminal ( barely makes the light glow) when the switch is in the hi beam position and the fuses are out. When the circuit is completed by connecting the holder terminals with light connected to both ends there is no current. When the fuses are inserted and the continuity light grounded to the frame then touched to the top end of the holder there is no current. Seems that whenever the circuit is completed by inserting a fuse or otherwise no current flows. Any ideas??????????? Help!!!!!!!

Don't have the wiring dia. here at home but if memory serves me correctly the combi switch(turn sig) powers up the fuses. Power flows from headlamp switch to combi switch to fuses. No power to fuses, then the combi switch is the problem.
