Turn Signal and Hazard Relay

As most of you know our turn signals go fast when a bulb is going out and lately mine have been doing so but I have yet to have a bulb go out. Whats strange is that when I hook up a trailer and tow(obvisously has tail lights), my turn signals will go normal speed, but only when its hooked up. This has been going on for about 3 weeks now. I had the fast turn signal issue a while ago and then a bulb went out but it didnt take this long. What I thought I could do was swap my hazard relay with my turn signal one being that my hazards go normal speed right now with or without the trailer. Would this work or is there anyplace I could get a new relay for my turn signals that doesnt go fast when a bulb is about to go out?

Did you switch any of your lights to LED's?
You can try the EP27 flasher relay, and see if that fixes the problem. Fixed my fast flash when I switched to LED's.

And as far as I know the hazards and signals are the same relay? I'm just guessing on that though.

Nope, all stock bulbs. What makes me think they are two different relays is that fact that one goes fast while the other one is normal.

It's located under the steering wheel, tucked up behind that plastick kick panel thing. My guess is switch to a ep27 flasher relay. Or wait till someone more knowledgable replies.

Per the 2001 Ford Owners Manual:

Turn signal flasher reprogramming information

During operation of the turn signals, if the lights flash faster or slower than the normal rate the vehicle has an electrical malfunction. The turn signal flasher can be reprogrammed by a dealer or qualified technician. The flasher may need to be reprogrammed if:
(a) the battery is disconnected, discharged, or
(b) a new battery is installed or the ignition switch was not in the OFF position when the trailer tow connector was disconnected. When the vehicle is used to tow a trailer, the turn signal flasher will recognize the additional lamps and will flash at the normal rate. The ignition switch must be in the OFF position before disconnecting the trailer tow connector to reset the flashers back to the factory-set speed. Failure to do this will result in the turn signals flashing faster indicating a burned out bulb.

I'd try reconnecting the trailer and wiring. Give the turn signals a couple of tries in both directions, then turn off the ignition switch first and then disconnect the trailer wiring. If that does not work, try disconnecting the battery for about 30 minutes and see if that will reset the system.

Thanks I'll try that. I can see how that can affect it and im not sure if maybe i left the truck on while taking the trailer off. ill see what happens
