This can be used for either the back-up lights or the brake lights.
There are a couple of ways to track this down. Of course, make sure your fuse and bulbs are in good condition. Disconnect the wiring to the switch. Measure the feed wire and make sure you have 12 volts. Note: Make sure the key is turned to the RUN position so you have juice to the wire. If there is no voltage, trace the wire back to the fuse and find out why! If you have 12 volts, connect a jumper wire of the correct gauge to jumper the connector. If the lights come on, it looks like a bad switch.
Put the car in reverse and use an ohm meter to check the resistance in the switch. It should be minimal. If not, replace the switch.
If everything looks good back to the bulbs. Go to the next step.
Disconnect the two bulbs and, put the car in reverse to engage the lights. Note: Try not to do this with the car running. If you insist, have a buddy with a strong, steady foot and chock the tires. Someone needs to be in the back measuring the power!
Measure the voltage at the socket. It should be about 12 volts. If it isn't you need to trace the wires back to the switch. If you see 12 volts, install one of the bulbs and remeasure the voltage. It may be that when there is no load on the circuit, everything looks fine. When you put a load on the system and the voltage drops, you have have a bad connection somewhere. Check your ground connections on the lights and check the connector at the switch.
2001 Mazda 626:
On a 2001 Mazda 626 (and I suspect many other), there is a relay in the fuse box under the hood. It is labelled the TNS relay. If your horn or headlights still work, swap the relays between one of them and the TNS relay. If, after making the swap, your lights now work and your horn does not, you have found the culprit. Unfortunately, neither Advance Auto, Autozone, O'Reilly, or Carquest stocks this relay. Some can order it - $19 and change at Carquest.
You may have a wire that is grounding out on the frame of the body, may take some checking to find it. gl check for rusty wireing or breaks in the wire, may take some time.
Where is a principal fuses to cigarrete port in a front suzuki XL7 2006 no working and fuses is good?
Try the dimmer switch, and or, check that your body has a good ground to the frame, and battery.
Answerit could be because one of your tail lights, brake lights, reverse lights, etc. the dash light goes off to let you know this. there is nothing wrong with the dash, probably. then again i have also seen minor electrical parts fried that cost an immense amount of mula. try the lights new answeri hit a deer once and that same thing happenned to my '88 century. I ended up replacing a fuse in the dashboard fusebox that, in the manual that came with the car (if i remember correctly) did not directly correspond to either the dash lights or rear lights. only after checking ALL the fuses and after the replacement of this supposedly unrelated, yet obviously blown fuse, they worked.My wife decided to jump start another vehicle during our ice storm and burned the contacts in the light switch.. which was the contact to bridge the dash/taillampsNew answer:I had this same problem with my 1990 Century. All my lights worked (except dash/tail) and my fuses were good. Replacing the head light switch took care of the problem. I hope that helps
In the fuse box located under the driver's side dashboard. That fuse is between circuits for air suspension, dash, lights, and a few accessories. Use a multimeter or lamp to find the blown fuse.
Replace the headlihgt switch, it's a common problem
Column Switch
I have a 1991 Chevy surburan and it has no tail lights and no dash lights, all fuses are good
try a test light on both sides of the fuse, tail and dash lights are on the same circuit
Probably the dash fuse is blown, or the dimmer switch for the dash lights is bad!
dash panel lights working? all fuses ok?, check on the fuses box under the hood it's a number 10 red, check if keeps blowing up
It could be the dimmer switch that will adjust the dash lights
I have a 97 Buick Park ave and the dash lights went out ? all other lights seem to be working , and I cannot identify which fuse , if any could be in need of replaceing . I cannot , with the owners manual , identify which fuse it is that controlls the dash lights ? there are too many , fuses with confusing acronyms ? Any one know exactly which fuse I need to check ?
1995 Chevrolet Monte Carlo no tail lights or dash lights they will come on at time and go off the fuses are not bowed. The tun singles and flasher and brake light work. What should I look for now?
bad switch?
If the fuses are all good (which, I bet they are), you most likely have a faulty dimmer control. Almost all the dash and interior trim lights are wired through this switch to allow you to dim them. If it has gone bad, that could cause them all to stop working. Fairly inexpensive and easy to change. Check the fuses-- under the dash and/or under the hood.
Switch most likely.
u may have a defective multifunction switch
