1996 Mercury marquises turn signal problem!

Having a problem with my 1996 Mercury marquises turn signal. If I engaged the turn signal completely where it will automatically return to neutral position. It doesn't work! If I engage the turn signal partially where the Arrow on the panel is just illuminated. It works fine. The owner's manual shows the plug-in Flasher located under the dashboard with the fuses. But it's not their just a vacant slot. Had local mechanic check , and he indicated the Flasher was located in a separate module that cost close to $350. Since the turn signal works when I do not completely engaged it , could it be something other than this expensive module?

Thank you.

It's not your flasher, if it was it would not flash in any position. However
the turn signal switches are known to be problematic in these cars. You can find them on Ebay for about $60

Yep, I had a similar problem in my 93 Crown Vic. Replaced the entire multifunction switch, and the problem was fixed.
