Your problem probably is with the combination Switch on the steering column or the AAM.

It can't be a fuse or relay problem because the right and left tail light are operated by separate relays and fuses. But check them anyway.

See that relay K5, K9 and K13 are in place.

See that fuses #12 and #24 are in place and not blown.

If all the above are good, remove the plastic covers surrounding the steering column and access the electrical connector to the Combination Sw.

1. with the key in pos. #2 or the eng. running check the GREY wire in pos. #8 for 12v.

2. then turn the light switch on and check the GREEN wire in pos. #4 and the BLUE wire in pos. 6 for 12v. If these two wires do not show 12 volts, then you need a new Combination Sw.
