93 940 Wagon Tail Light Issues

Dalpatine · Post by **Dalpatine** » 21 Mar 2015, 10:21

Hello,

I have been having issues with the driver side tail light assembly. I have replaced all bulbs, the bulb failure relay, and still I have no brake lights or running lights on the driver side. The car has 260,000 miles on it but is in solid shape with very little rust. I am thinking my next step would be to replace the entire assembly. Any help or ideas, especially a detailed wiring chart of the colored wires would be very helpful.

Thanks all!

Use voltmeter to see if power is present...if so, find/clean ground.

All,

I installed a new tail light assembly and all the lights are working as they should, but I'm still getting a bulb failure light on the dash, this is after I also replaced the bulb failure relay.

Any ideas?

That device is in effect measuring a difference in amp draw, aka wattage.

All replacement bulbs must be of OEM wattage specs....also, if oxidation/etc exists on a bulb, or its receptacle, less current draw will be "seen" via that device.

Might use electrical contact cleaner on the dirty bulbs, and their receptacles.

Alright,

I will try this and see what happens. Thanks!
