Turn signal flasher doesn't work in the heat. What gives?

All lights work. Turn signal stalk works fine. It just flashes a couple of times, then stays on. Everything works fine in cool weather, but it rarely works at all when the temperature outside is above 90 degrees. Very annoyed.

 

Happened to me. It is the flasher unit. Do a search on how to find it. It is a blue relay but inside a black box behind radio and lower down in dashboard. About $35 at Ford dealer. It is overheating.

 

i for the life of me couldnt find mine looking up from under the dash so i took off my dash bezel.......this will help you find it from the underside.....





right there inside that little black box is where the relay is.......

 

Prompt and helpful, gentlemen! I'll post back here if I prove to be too dumbtarded to locate the thing. Thank you very much.

 

Napa has that relay for about $15 or so? I replaced mine a couple of years ago. EL-27 I think was the part number. It's a little taller than the Ford blue relay so you won't be able to put the black cover back on.
