    turn signal/high beam stalk problem

    hey guys- i have a problem where the high beams will come on when i pull the stalk backwards (momentary flash) but when i click them forward to leave the highs on, nothing happens. do i need a new stalk or a new relay?

    thanks!

    posting and update because this still isnt fixed.

    I went ahead and replaced the stalk + stalk relay, as well as the K3 (high beam) relay in the fuse box and the problem persists. any ideas?

      That is strange. I would say the wiring to the lamps are okay since they come with the momentary switch. Download the ETM and see what the circuit looks like between momentary and full ON.

        Yeah I figured that's where I'd dig next. Heres the ETM:



        It appears that the switch does take a different path based on flashing or switching the highs on, so it looks like a bad Low Beam relay or wire connection to the fog light switch may be the culprit. Does someone with more expertise in ETMs agree?

        If i recall, one of the POs bypassed the regular fog light wiring and ran some new wires in order to bypass the check and allow them to use independent fogs. Am I screwed?

          Find the location of C202 and C103 in the ETM and check the wires/pins for corrosion or breaks.
