I have a 2007 Mercury Grand Marquis GS. My left directional suddenly blinks very fast.
I went to make a left turn last night and the left directional started out at normal
cadence and suddenly switched into a very quick cadence. I thought that Relay 1
(fuse box) needed to be replaced but that didn't solve the problem. But I noticed that
once I replaced Relay 1 my electric/power windows stopped working. The original
relay 1 was a 4-pronged relay - the replacement is 5-pronged (a male connector in the
middle). Do I need to clip off the middle prong on the replacement? Do you know
what can be causing my left turn signal to blink very fast?
