when you remove the ignition key , it should tell the corrupted lamp on the OC screen.

 

Only if the OP has an on board computer.

Not all 75s and ZTs have them

 

Double-check the rear lights. If a bulb blows, the OBD system turns on the brake light at low power to double up as a temporary rear. At first glance, everything looks OK until you check which bulbs are actually being used.

EDIT: Sorry, I misunderstood your problem. Ignore the above (or take a mental note for next time).

A front lamp can go if the wiring chafes on the badywork behind the bumper. Fairly common issue. Needs bumper off to fix.

Double check all bulbs. I replaced one in the back and the warning light still kept flashing intermittently. I went through them all again methodically and found one that was difficult to fit. I think there was a fault in the holder gripping the bulb. Once I managed to sort it out everything returned to normal and no more warnings.

If tghe bulbs not in the circuit, then you won't have any current flow, have you checked for volts at the bulb holder?

As other have said, you may have a chafed wire that has worn through and is losing the circuit to this bulb holder.

Yes have checked for volts at the front and there's nothing so I'm guessing the bumper may have chaffed the wire?!?!? Looks like it's bumper off then

Dunno how I'm gonna break it to the wife, I've only had the car two weeks and she's already complaining I'm spending too much time on it (servicing, cleaning other niggly faults!)

Thanks Guys

Will let you know the outcome when she lets me do it!!!!

 

Finally got round to checking behind the front bumper and sure enough wire chaffed through on bodywork! Thanks T-Cut and Robdrinkwater, pretty easy to fix in the end
