Turn signal problem.Fixed all bulbs and made sure flasher relay was working.all running lights brake lights reverse lights work and hazards work.but I get nothing on dash or lights when trying.

Double and triple check the fuse for your rurn signals both visually and with ammeter to check for fuse continuity, or just replace with new one of same amperage. The fuse can look good but have a hairline crack that is not visible.

No check engine light, bulb test good

wow, no jeep stated. nor what year, nor what engine.

ill not even beg country (exports are diffr)

below is all ways, discounting bulb tests.

i guess you mean the key on only self test fails with CEL?

ok the PCM glows the lamp at key on, to tell you the PCM is happy and that it passes its rudimentry self checks

basically means its alive.

if the lamp fails to glow ? (all ways, i fix ECU so know this)

  1. power to lamp dead (fuse ) yes fuses can crack (unseen)

  2. lamp bad, (test it with a battery)

  3. cluster wiring to lamp bad, or that wire from PCM to lamp bad.

  4. ECU bad, yes, some bad ECU's can run an engine.

  5. ECU stuck in backup mode, (think limphome but 2 times worse)

in your case id say bad ECU, or bad wire from ECU to CEL.

no year stated, so is it 1988 with that silly junk RENIX EFI with no working CEL or is the unstated car 1993+ where the CEL started working for the first time?

if 93 or newer, we can connect a scan tool, and scan it.

and see , omg , comms are dead, so ECU is in backup mode.

(backup mode is like lawn mower mode, sure it runs but like crap)

ask? can give vivid details of all modes.....

or comm's is ok, and scans and we see DTCs stored and the CEL status in the scanner says ON,"aka, active CEL"

if it says ON< and is not on, then the wire is bad or the

CEL transistor in the ECU blew up. (common with folks using wrong bulb and overheating this poor transistor) replaced many i have.

there are some facts. and is poorly stated. due to NO YEAR !

Won't power up and fuses inside are good. What's wrong? Worth fixing?

You can get the service manual free online. Just type your model number and the words "service manual".
From what I've seen it has a test mode you could try. There's also a thermal fuse on the transformer, which you might not have seen.
I have the earlier version of this model the 602 and if yours is like mine it certainly is worth fixing. I suspect the only time these things are not worth the money is when the massive chip inside them goes. But I don't think that has gone in your case.

If you have any problems getting the service manual comment below and I will send it you.

Stop lights not working

Check bulbs and fuse first than test your brake light switch .usually the vehicle cant be taken out of gear if fuse or switch are bad. The best way of testing would be with a 12 volt test light. The light can be bought at any auto parts store under $20.00. Hook one end of light to ground (metal unpainted on truck) touch the other end on fuse touch metal connection on both sides of fuse (one side at a time )with key on . Test light should light . if it only lights on one side the fuse is blown and will need to be replaced. If all is good remove tail light bulbs. have someone sit in truck with key turned to on. Ground the test light and touch the point of test light to conection in bulb recepticle on truck it should light on one side when brakes are pushed .there are 2 metal connections in resepticle the other one is running lights. test with lights on. one should light up for sure. if the test light lights with both all is good bulbs are for sure bad. if this was helpful please leave good feed back

you need to check if there is power in the brake light wires in the trunk. find the brake light bulb and use a automotive test light. have someone push the brake pedal or you can block the brake pedal down and see if there is power. The tester will have a sharp point one end and an alligator clip on a wire at the other end and a bulb in the middle between the two. if there is power when the brake pedal is applied the test light bulb will light then your bulbs and or sockets are bad. Be sure the bulb sockets are not corroded or rusty.
I can't tell you how many times I have seen it be simply the bulb. Either the wrong bulbs or installed incorrectly.
Otherwise try to find a repair manual (haynes repair manual any auto parts store about $20.00) for this vehicle and it will show you the entire circuit. Be sure the fuse is good and there also could be a relay, often found under the hood in an electrical box near the battery. sometimes there are identical relays on different circuits so you can switch them to see if that was the problem. before opening the electrical box you should consider removing the negative battery terminal making sure it cant contact metal/ground and re energize the system. I don't remove the terminal but you must be super careful not to short anything out when you un plug or re plug the relays. never use a metal tool to try and pry the relay from it's spot . pull gently and firmly straight out of its plug / usually up. The manual will tell you if there is a relay but also usually the electrical box lid, decal inside, will tell you what the relays do. good luck. be careful not to short anything out. That will cause even more problems like engine control brain damage and that's expensive.

Rear left turn signal and brake light does not work

Use a test light to test the socket at the problem,see if there is 12 volts at the socket.Also,make sure the correct bulbs are being used,the wrong bulb will not make contact.

2001 ford taurus ABS will not light but brake light on

You have a bad ABS module. Had the same problem with my 2000 Taurus. The ABS module is a Bosch 5.3 You can have yours rebuilt for $170 or go to a junk yard and pull one from a 2000-2003 Taurus. Make sure its a traction control module if you have it on your car!

Brake and tail lights

Pull the light bulbs and test the bulb sockets, use a 12 volt test light probe, kinda looks like an ice pick or awl, with the clip lead of the test light at a good ground, probe the contacts to the bulb with the lights on, if the test light glows then there is 12 volts to the socket, if not probe the wire to the socket for power, if it is ok then replace the bulb socket, the dealer can supply this part. 1st though make sure the bulb is good, swap out a working bulb to the non working side,
