1992 Toyota MR2 Q&A
1992 Toyota MR2 Question: How to fix both backup lights not working? Bulbs and fuse good.
There is a switch on the transmission with two wires on it. It is the reverse light switch. When the two wires are bridged together with the key on the reverse lights should work if the switch itself is defective. It is quite easy to replace, it just unscrews from the transmission if it is a stick shift, if it is an automatic transmission the switch I believe is part of the inhibitor switch and is more costly and difficult to replace. Tell me what transmission you have and I will tell you the test procedure and color of wires to bridge to determine what is wrong. - patrick mannion
My reverse lights on my 93 ford escort are not working. The fuse and lights are good. What is my next step to trouble shooting the problem? - Visitor
check the transmission wire connection. on the 91 turbo it is located on top of the transaxle. last time i replaced the clutch i missed hooking it up and, no back up lights! it is almost impossible to see without a flashlight and mirror when everything is put back together. other than that there may be a relay in the excessory fuse box and if so they are expensive. about 40.00$ each for mine. - Visitor
Yes, the wiring could be shorted or broken to brake lights from switch or no power to switch. But if you did what Patrick stated, you should check with an volt/ohm meter for voltage or open to bulb circuit. - Visitor
