Hey all! I'm new here but i am not without a problem. I have a nissan 300zx and as i was driving down the road, i went over some railroad tracks and all of a sudden my a\c control and the front and rear windshield wipers went out. nothing comes on as far as those 2 components go. they did come back on after a couple of hours but then i went for another cruise and they just went out again and this time they havent come back on yet. i dont know if the a\c and the wipers are on the same circuit or on the same relay. i have checked all of the fuses and the relays and they are fine. i tried going over the railroad tracks again and nothing happened. i would really appreciate any advice or help u could give me on this. i am good at this sort of stuff but it has me really stumped. i live in texas and it hasnt gotten cold yet so the a\c is really neccessary. thanks for your time.

 

You have a loose connection somewhere and will need a wiring diagram to diagnose it properly.A thorough exam of the fuse panel may be a good place to start.Look for loose fuses or corrosion on wires(front and back of panel).Also check every ground you can find and clean it and reassemble.
