When I turn on the right turn signal on my 2007 Entourage, it usually works OK, but sometimes it flashes extremely fast. The left turn signal works fine. I suspect there's a problem with the flasher unit. But where is it located? Thanks.

Unfortunately, the flasher unit is integrated on to the BCM from what I understand. That means you have to be a wiz with a soldering iron and know where to purchase the correct component, or you just buy a whole new BCM. Look in you owners manual, fast flashing might mean burnt out bulb or something.

Yea normally a fast flashing sensor means you have a burnt out bulb. Might be worth spending the $3-5 and replace the front and rear turn signal bulbs, or if possible check both the rear and front when its blinking fast to see if either of the bulbs aren't working.

Thanks to both of you. You were right. The problem was only a burned out bulb. It was a relatively easy fix with directions in the owner's manual. Euphonius.
