Thanks so much for looking at this post, I am desparate. This problem started a little over a year ago, I had no idea how to fix it, so I took it to a local electrical diagnostic shop, $240.00, told there was a short in the system, needed to take to the dealer. Took it to the Ford dealership last June, $380 to replace the mulifunction switch. Worked again, but then brake light on dash would act weird on and off for no reason (may be no connection to problem). Anyway, worked for a year and a month, same problem, call Ford, replacement parts are only warranted for one year, I was a month late. Talked to head mechanic, he said it was deffinately the same problem as last time. Bought a brand new multifunction switch, installed, same exact problem, besides having a shiny turn signal switch and a few less screws in the column cover. Exactly the same. So back where I started, any help would be appreciated. As of right now the following things do not work: turn signals (front and back, rapid blinker on dash like when bulb is out), brake lights (except center light above trunk, dash brake light no longer comes on either), hazard lights (these blink at normal speed on the instrument pane)l. Thanks again!

Did you make a close visual inspection of the two connectors that plug into the switch to see if they were melting/burnt? Sounds like high resistance in the connector's terminals causing repeat failures.

First off, thanks for the reply.

Yep, all looks good, no signs of shorts or burning or melting, pretty clean, actually. I followed the wiring back into the dash from the column and there is another coupler or splice about 10 inches in, I am nervous taking that one apart to check, it has foam secured around it and seems fairly odd to open. Is this coupler safe to inspect?
