Both rear brake lights, rear turn signals, and rear hazard lights not working

Hello,

If the fuses are good it sounds like the GEM is out and needs to be replace. here is the location and instructions on how to replace it below. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Looks like the hardest thing to do is to figure out how to afford a GEM change. I need to find someone that can remove the data and put it in the new one. Ford dealerships charge a ridiculous amount. If anyone has any suggestions, is this something I can do with the right software?

Not really, you must be able to transfer data. I have heard of some success trying a used unit but I cannot confirm if it will work 100% Try calling around to different independents to see what they can do and let me know.

Good news, I did not have to replace the GEM. Thank you Jesus! Talking to a mechanic at a local shop he said he wanted to start from the beginning. He check the fuses and wiring and all was good. Then he check the bulbs. I told him I put new ones in. Bulbs were good, however, he said he wanted to try a different bulb anyway. He changed from a 3157 bulb to a 3057 and it worked. Say what?
The book in the parts store calls for a 3157 bulb, what I pulled out of the car was a 3158. Parts store didn't have a 3158 so I went by the book recommendation 3157. Apparently the book is wrong. The mechanic said something about how he prefers the 3057 for some reason I can't remember. I was just thrilled it works now!

Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help.

Just got the car home from the shop and had no hazard flashers or turn signals.

The system goes through the Generic Electronic Module from the fuses and turn signal/hazard ight switches.

What is that and where is it located?

It is a small box for controlling a few functions and is located at right side A pillar.

Heres a guide on turn signal problems, it will help

Attached below is the wiring diagrams for your turn signals

Do you have a diagram for the location of the relays in this. I cant find one anywhere. I have moved around the relays that are same and still nothing. Is there a seperate relay for hazards and turn signals

There is not a relay in the GEm for the turn signals or hazard flasher. There is only a fuse and it is good. Also have changed the turn signal switch on the column still no turn signals or flashers. Any help?

The GEM is a control unit by itself and do not have any relays that are detachable. You need to perform wiring and power supply checks. You mentioned getting the vehicle back from the shop. Waht was done at the shop and was problem there before sending it in?

Are you able to perform checks with a DVOM or test light?

my left side bleaker light , turn signal, and hazard light does not work

Had timing belt and water pump replaced.

Have you checked the bulb ?

Did the hazard and turn signals work before the work?

yes. and I try to see if there were any broken fuses also

Yes as far as i know they did.

Disconnect harness for that side and check for power and ground on that side

How will I know how the Harness look like ?

Which is it front or rear ,right or left that ins't working ?
