    Hey gang,

    I was out yesterday enjoying a long drive on a beautiful (but unusual) New England August day (78 degrees and low humidity). I noticed that I got a couple of dirty looks and a couple of "use a blinker A**hole" which of course I thought I was. I noticed the next turn when I looked down at the dash after depressing the turn signal, nothing was happening. I pulled over and check to confirm they were not working. I then checked the brake lights which were working. I pulled the fuse and replaced it, but that was not the issue. I then continued home and about a block from home it started working again. I am assuming I have a loose connection or a short somewhere (or perhaps a bad relay). Any idea where to begin looking? Is there a relay for the turn signals that could be going bad? Any suggestions would be appreciated.

    Joe

    Joe,

    Pretty common problem...

    The next time this happens, see if you 4-way flashers work; likely they won't. However, if you turn your 4-way switch on and off a few time, the oxidation on the switch will be removed...and both the 4-ways and turn signal will work. You could a) replace the switch b) Ignore the switch and just turn the 4-ways on and off a few time in the beginning of the driving season or c) spray a little electrical contact cleaner in the switch. (Current for the turn signals flows through the 4-way switch...)

    Or...look under the far left side of the dash of the dash and see if the 4/6 pin connector from the steering column switch has worked its way loose. Pretty common, as well.

    Best,
    David

    David,

    Thanks. Been driving the car this week and the problem has not returned. I printed this post out and put it in the car for the next time the gremlin returns.

    Thanks again, Joe

    Joe,

    You're welcome. For what it's worth, I have had this idential problem, every year, with my BB...when I first take her out in the Spring, after the long Winter hibernation. The 308 and BB have identical wiring, with respect to the turn signals/4-way circuit.

    Best,
    David
