If it shines brightly, then you probably don't have a drain. If it's slightly dimmed that may just be normal current driving thing like a clock. You can methodically remove fuses one by one (checking the test light each time) to see which component may be at fault. If none of that pans out then have your alternator checked. tidester, host SUVs and Smart Shopper |

Hello I'm having some new issues with the turn signals on my 2000 GMC Jimmy SLT 4DR. they stopped working today all together. I figured maybe a blown fuse..checked #10 turn signal 20amp fuse looked fine..switched it anyway..still no turn signals at all. anyone know where to check first? I'm thinking maybe the turn signal switch, it seems to work ok for high beam after it glitched a bit. also I have an intermittant problem starting where it won't stay running then fires this has happened maybe 6 times total.

Replying to: repairdog (Aug 29, 2006 2:24 am) thanks for the reply, I found the flasher behind the glovebox in the lower RH corner, apparently somehow my hazard switch got bumped when I trip the hazard switch one way I have my turn signals back and can feel the flasher clicking but in other position I have no turn signals or hazards I can feel the flasher relay click slightly when I engage the hazard. any idea if the same flasher relay runs the hazards as well, it appears maybe that part of the circuit is malfunctioning. Re: starting issues it has a trailer plug in that has been on the truck since my dad bought it but no recent additions not sure about the security light I tried turning the alarm on & off when it occurs but doesn't seem to change anything. my dad passed away last year so unfortuantly I can't ask him anymore. I saw someone mention the key switch on one forum, but it happens so randomly it's wierd. thanks for helping out I was suspecting the turn signal switch assy maybe I just need the flasher/hazard? relay |

| today I went to start the Jimmy and the ignition key cylinder locked up on me with the key inside the lock. I couldn't remove the key or lock the power locks so no way to lock the hatch in back manually. after removing the lower dash and steering column plastic I noticed a cap on the lower column plastic cover after removing it there is a gold colored pin upon depressing it I could remove the key. intially the jimmy still wouldn't start but did eventually tried starting it a dozen more times and it fires up and power door locks function. I'm suspecting the ignition & start switch and ignition key alarm switch (as the service manual calls it) where that gold pin is located I can see it move in & out when I insert the key appears to be some sort of solinoid. any ideas ? | |

Replying to: repairdog (Aug 31, 2006 1:27 pm) the culprit to my problem becomes apparent the plus side battery terminal was ever so slightly loose and had some corrosion that wasn't apparent from the outside, but it was just enough to give me a bad connection and intermitant problems. feel somewhat stupid I didn't find it before that but thought I'd pass on the info. the Jimmy didn't act like it was a battery ( no clicking solinoid or slow cranking or the usual symptoms ) I cleaned the terminals with some baking soda & water and then rubbing alchohol put some new anti corrosion washers on. and wala 14 volt reading on the voltmeter without changing out the alternator (with the Jimmy running). |
