Hi I have an older EXCEL. My relay under the dash (STEERING WHEEL)was bad..it controls the rear lites if the fuse is NOT blown..its a gold color relay..there are 3 on mine..all have the same part number,they r a bit hard to reach, but swap one out..if your relay is bad, the other one with the same part # should work your lites if that relay is bad..the FUSE itself should be on left drivers side floor near clutch pedal..i don't know if your car is the same. Mine is a 1992 EXCEL..good luck
Yes

Answer 1 - Instrument Lights Operate IntermittentlyWithout doing a "hands on troubleshooting" of your vehicle, no one here can be certain of the specific location and cause of your problem. However, based on your question, I suspect that the cause is a loose connection in the circuit providing power to the instrument lights, or on the instrument panel circuit board itself.It is possible also, that the instrument panel dimmer switch is wearing out.Answer 2 -The dash dimmer switch or the headlight switch is the most likely problem.
Bad ground, Bad Battery. Or The battery was connected improperly. I.E Reverse Polarity.
AnswerIf the bulbs check out OK then I would check for a loose ground wire.Replace your turn signal switch, that's what I had to replace to get mine working again.
Bad bulbs can be the cause of your reverse lights not working on your 1999 Toyota Tacoma. A problem with the reverse switch or bad wires can also be the cause of your reverse lights not working.
head lights won't work, no power to them, signal works , reverse lights work
Reverse light switch bad or out of adjustment.
Did you check the light bulbs? If OK, probably a bad reverse light switch in tranny.
There is a switch on the shifter or trans that turns on the lights when the vehicle is placed in reverse, it is out of adjustment or faulty. And don't forget the bulbs or fuses as a cause.
In those tail lights there is a circuit board. If it goes bad it will cause all kinds of problems.
Cracked electrical wire caused this to my car once.
Perhaps something in the gear shift that turns on the lights when in reverse position.
try the neutral safety switch
Check your fuses. If they are all good and none are blows, you probably have a short somewhere in the electrical lines.
ck bulbs first then ground circuit and power on trunk lights.Ground most likely
Check the fuses first. If the fuses are ok check the reverse switch. The switch is under the dash on some models, and on the transmission on others. A bad or misaligned switch is the most likely cause for no back up lights.
