Multi Function turn signal/high/low beam/wiper switch

Blinkers quit working, so I replaced the multi function arm. No change.Any suggestions? I did take the arm apart, found considerable corrosion, but nothing that I could see that would be causing the problem. Replaced the unit to be safe.Four ways work, bulbs all good, fuses good, wiring is good.

The turn signal circuit has it's own flasher/blinker. It is located on the fuse panel under the dash. What led you to believe the MFS was the problem?

The truck sat, untouched, for 6 years in a very wet environment. With all of the corrosion I have found, I didn't want to put the old one back on. The fuses are all good. I checked those right off the bat.

Be sure the Hazard light switch isn't engaged.

Not the fuses...I was referring to the flasher itself. It's the round canister on the lower right of the fuse panel.

It needs to click while the turn signal switch is engaged. If it doesn't click replace it. You should be able to hear it, or feel the click by touching the can. I would also replace it if the turn signal indicator light doesn't flash, but remains lit while the turn signal is engaged.
