Paging JP or any Ford F-150 People

Today I noticed that my turn signals and brake lights don't work. any thoughts? 2000 F-150. Thanks in advance.

Fuses, Relay, Trailer Light connection for the wiring goes to a T-splitter. I'd try there first

The MFS has a tendency to heat up at the connection under the wheel cover. Pull the cowling under the steering wheel and look for a white multi wire plug that is now mostly Brown from heat/scorch.

You can do an easy fix by buying a box of Spade connectors from Auto parts store or Radio Shack and cut off the plug end on either side and crimping/soldering on the spade male/females and plugging together. There is usually enuff loose wire to do this.

Same desighn was used on Ranger and is a known issue.

If it is still under warranty there is a FoMoCo TSB on this.

One more thing, the brake light came on. Could that be caused this problem?

sounds like it. brake light on would seem like that is the case. I'd check the fuses etc first though. a little bit easer

The Multi Function Switch was where I was going to point...good call!

The brake lights do work, it's just the turn signals.

[Aquaticedge]

Flasher relay possible then the MFS too I'd hazard a guess

Obviously you are out of blinker fluid

I've been out for a while now. I been peeing in the reservoir for months now.

Emergency flashers work, but the turn signals still don't.

[Aquaticedge]

there is a seperate Flasher relay for the turn signals. Check it
