Turn signal/Hazards problem!!

Hey all,

It's my first post here, and I got a doosie...I did mucho searching and found only comments on replacing /repairing flasher relay located behind knee bolster. Well I played the game and replaced it and I still have my problem.

PROBLEM: Turn signal engaged to right works great no problem, LEFT turn signal engaged the front blinks correct BUT both rears are flashing...no bueno

Please tell me where to start...I have a test light /voltmeter and some mechanical background. HELP

Thanks-
ps...I really like all the info here and hope to learn more.

When you engage the left turn signal, you get the left front to flash, but BOTH rear signal bulbs flash. Is that correct?

If so, its almost certainly your "multifunction switch", which is what controls both the turn signals and 4-way flasher. My description above is a common failure mode. A new switch should fix the issue.

So would this be a sufficient replacement or should I go to NaPA? http://www.oreillyauto.com/site/c/de...2100&ppt=C0039

Thanks by the way AZ Jeff I really appreciate it.
