Can someone help me locate the flasher relay? I have been racking my brain for the past two hours trying to locate it underneath the dash!

Thanks, Dave

 

Here is a thread, that was for the EATC not working correctly, which the Aux relay block #4 is the same one for the blower motor relay, and the signal flasher.

The 2 locations the EVTM lists AUX Relay Block #4 being are in this thread. Short answer(s) :
1. Under the LH side dash, Seemed like above the parking brake.
2. Center behind the dash, sounded like where the Autolamp sensor & the power window relays are at, under the oval under the top center of the dash.

I was to say I saw the AUX relay block #4, around where the parking brake is at. If nothing else, drop Screw-Jake an email, and ask him to be sure. He found this some time ago. He said it had a cover on it, so it might not be overly obvious straight away.

Good luck.

 

Thanks for the help SSCULLY. I ended up finding it just centerline of the steering column. The flasher relay is blue for the 2003 F150 and it sits in a small plastic bracket alongside a slightly smaller black relay. The replacement relay cost me just over $20.
