Replying to: kiawah (Jul 04, 2009 6:02 am) - Battery is good, brand new with new terminals - 100A fuselink is good and brand new - 40A AM1 fuse is good an recieving power (doubly confirmed with multimeter and fuse tester and my alarm went off when i plugged it back in so its completeing the circuit.) - Hazard flashers do work So we are still at were we were in my first post, just know that the fuse and fuselinks are good. Thoughts? Thanks for your help

Replying to: iconoclast187 (Jul 04, 2009 9:26 am) - the power from the 100A fuse link goes to two circuits. - the first circuit is to the AM1 fuse as I mentioned. That AM1 fuse feeds one of the wiperlegs (the AM1 leg) of the ignition switch. That wiper leg of the switch connects to: - - the ACC post of the ignition switch, which then powers the 15A cigarette fuse, the 15A power outlet fuse, and the 7.5A rad #2 fuse. Verify that you have power to the cig and power outlets, they're easy to check. If so, that will tell you that the ACC post of your ignition switch is good. Ignition key obviously needs to be in the accessory position. - - the IG1 post of the ignition switch, which then powers the 25A wiper fuse, the 10A Heater fuse, the 10A Gauge fuse, the 7.5A Turn fuse, and the 15A ECU-IG fuse. Verify that you have power to the input of the 25A wiper fuse, if so, that will tell you that the IG1 post of the ignition switch is good. Ign switch obviously needs to be in an ignition position. - The 2nd circuit fed from the 100A fuse link, feeds: - - the 25A door fuse - - the 30A power fuse - - the 40A defogger fuse - - the 7.5A OBD - - and the #5 and #1 pins of the taillight relay. Pull one of those fuses, perhaps the 40A defogger or 30A power, and verify that you are getting power to the input of the fuse. That will confirm that your wiring is making it to that buss. Let me know what you find in each of those two circuits.

Replying to: kiawah (Jul 04, 2009 10:09 am) That 25A wiper fuse mentioned above, is tied directly to pin 2 of the washer motor. The pin 1 of the washer motor is what gets grounded out by the switch to to turn the washer motor on. That 25A wiper fuse, also is tied directly to pin 2 of the wiper motor plug, so that's another place you can verify that power is making it all the way thru that wiper fuse.

Replying to: kiawah (Jul 04, 2009 10:22 am) Current status - Starts and all powertrain components function - blinkers, hazards, wipers, interior gages all function (far as i have noticed) Not working - headlights - power windows and door locks but this is a good improvment since i can actually drive to the grocery store now heh. Thoughts?

Replying to: iconoclast187 (Jul 05, 2009 7:12 am) You may want to swap out your 10A Gauge fuse, with another 10A Gauge fuse. That circuit feeds a lot of control circuitry, I want to eliminate that fuse from being a problem....even though it might look okay to you right now. I'd feel better if we had actually found a failing component above. You need to verify that power is getting up to the second circuit as mentioned above in note 584. Pull those fuses and check that they are getting power fed to them from the buss, and that they are okay. Also check to see if your rear brake lights are working or not, and whether your rear 'running' lights are working (the lights within your brake lights that come on when your headlights are on).

Replying to: kiawah (Jul 05, 2009 7:20 am) My break lights are working, however the rear 'running lights' are not.

Replying to: iconoclast187 (Jul 05, 2009 9:23 am) Do you have Daytime Running Lights, or not? DRL = front head lights that are on all the time during the daylight hours

Replying to: kiawah (Jul 05, 2009 9:39 am) Check whether your glove box light works or not. I suspect not. If it does NOT work, then verify that the 7.5A Panel fuse does NOT have any power in the fuse socket that would power that fuse. If all of that is true and the panel fuse is not getting powered, then either: - your taillight relay is bad, or - your taillight relay isn't getting turned on by the integration relay. If the 7.5A panel fuse does not have power, then pull the taillight relay out of it's socket, and short in the socket from pin 5 (which should have 13volts on it in the socket), and pin 3. Pin 3 feeds the 7.5 panel fuse. When you short these pins, your glove box light (as well as the dashboard switch lights ...radio switch light, ac switch light, etc) should get power and turn on. You may have to read the pin numbers from the relay, and then be careful to choose the right corresponding pins in the socket. If you are not sure of the pins, then do not jumper the socket. Alternatively, if you understand how relay's work, and have an ohmmeter, I can walk you thru how to test that your taillight relay is good or not.
