#76 of 6379 Reverse Sensors by haycar Dec 07, 2000 (6:44 pm)
Has anyone installed a reverse senor on the tahoe? Either Ultrasonic or Sonar based. Which brand, pricing and where did you find it? I bumped into my bros minivan, luckily no damage on either car. thanks in advance.
#77 of 6379 Fog Lamp/Rear Wiper Problem by cwmartin Dec 07, 2000 (9:27 pm)
I heard back from the shop foreman at Northpoint Chevrolet about the problem with my Yukon and the rear wiper doing a quick engage/disengage whenever I turn on the fog lamps. Unfortunately GM will not a let a Chevy Dealer do warranty repair work on a GMC Yukon, so I have to take the truck to a GMC dealer. The good part is that Northpoint Chevrolet did open a case number with the GM Dealer Technical Assistance center and they did give some things to look at about the problem. The technical assistance center said to: 1)Reference Electrical Schematic 8-250 2)Clean Star Washer inside the mechanism 3)Check voltage drop on Pin Connection E So now, I will find a GMC service center and give them this information and hope they can fix the problem. Hope the information helps out other people with same problem. I will make another post if I find out more information. Clifford

I forgot to mention that I was told that there wasn't a TSB on this problem yet. It takes lots of cases to be filed with the Technical Assistance center to generate a TSB. So if you have this same problem, get your dealer to file a case with the Technical Assistance center, so eventually a TSB will be created.
#79 of 6379 brush/tail light guards by jdh8 Dec 07, 2000 (10:26 pm)
does anyone (besides Ryan - thanks for the help Ryan) have any input on brush guards/tail light guards for a 2000 Yukon with cargo doors? I'm thinking about going with Waag's... what are the best prices people have been getting? I'm not sure if they even make a tail light guard that would fit on a truck with cargo doors.

I have done extensive research and believe the system below is my best bet. The information below was from their technician: Our system detect down to 8 inches. At this point, you will hear a very very rapid beeping. The digital display will show "hit". We use Ultrasonic sensors. The sensors can be mounted on the bumper or underneath the bumper depending on your vehicle. Our system will detect stationary or moving obstacles. You can get more information and purchase our system at: http://www.poronUSA.com
#81 of 6379 (fcornay) Side Mirror Adjustment.I` by don434 Dec 07, 2000 (11:48 pm)
I`m very thankful for great guys like (subliminal) since they have the product - all I can do is report what the year 2000 service manual says. GM must have had a couple of "make it cheaper" experts redesign the good mirror design they had in the 1992`s. I can line that mirror up so that while siting normally behind the wheel I see the following. On the extreme right mirror surface I see only my rear bumper and vehicles behind me about a car length back. The rest of the mirror shows the adjacent lane to my left. The mirror will still adjust further to the left but I don`t need that much coverage to change lanes. Had my brother drop by the local Chev. lot today. He looked at my mirror first - poped out the glass to see the adjustment and glass movement screws-and then surveyed the year 2000 models on the lot. They are nothing like my units. He could press on ether end - the mirror moved without any noise and he said that such little pressure was required that he doesn`t see how they stay in adjustment. Apparently they do though since no one has reported this problem (won`t hold adjustment). All we now have is a stupid design that won`t allow us to see the passing vehicles properly.Way to go GM.

andyl2, i have the poron on my 2Kyukon. The model I have "talks" to you at 8/5/3/1 ft and crash! It cost me 300$ installed some 6 months ago. Has been great.
#83 of 6379 RE:Post 82 Fog Lamp/Rear Wiper by don434 Dec 08, 2000 (1:20 am)
Very interesting trouble. Seem to remember looking at the two switch wiring schematics about a month or so ago. Couldn`t find a logical connection where : in operating the fog lights would cause a pulse to be connected to the wiper motor. I think I see where the tech. center is going. Drawing 8-250 shows two items with a " Pin Connection E " The Rear Wiper-Washer switch has two four position circuits. Switch position Pulse 1 has a direct connection to the wiper motor control module.Switch position Pulse 2 has a resistor in series going to the wiper motor control module. Both the Pulse 1 and the Pulse 2 switches feed Pin connection "E". If something is dumping a spike of energy onto Connection "E" this will tell the wiper control module to pulse once. The Rear Wiper-Washer switch receives its battery feed through the RR Wiper - 15 Amp fuse. Just for kicks Clifford could you remove this fuse long enough to turn on the fog lights and see if the wiper motor still pulses. Just interested To confuse things a little - the Rear Window Wiper Module (located in the Lift-gate Panel) also has a Pin Connection "E". This pin has a Black Wire - circuit 1450 - which goes to ground.Since under normal operation this ground is required to have proper wiper motion in all three modes of operation it would be good to do an ohm check to ground. As you no doubt know a star washer has several sharp edges which normally dig into a metal or aluminum mounting. The term clean the star washer seems a little odd. I would make sure that the star washer is tightly held to ground and that it is not very rusted. Hope to get out of this *#!%** bed in a couple of days. I wanted to send you a fax of the antennas but the fax unit is a stand alone in the basement office. Tried once to take the drip pack and the drain tubes with me but chickened out at the top of the Basement stairs. (Ran into secondary infections after donating the spare kidney.) If your still around for the 2002 Yukon / Tahoe shipments I hope to get one and will be very happy to run tests on my own toy.Thanks much for putting up with all my dumb questions. It has been a wonderful diversion for me.

Don: It will be sometime this weekend before I will be able to try your fuse trick. Which fuse panel holds the fuse I should try to remove (under hood or under dash). I wrote my original message while at work today and still have not yet had a chance to look up the schematic in my service manual yet for myself. I am taking next Thursday and Friday off from work, so I guess I will spend Thursday at a GMC dealer getting them to fix this problem, some brake squeaks, and to look to see if my Yukon is missing those rear wheel well plugs.

#85 of 6379 reply to #75 auto start by caseyjoe Dec 08, 2000 (2:30 am)
The other day I was early for an appointment so I waited in my 00 Yukon with engine and ignition off listening to the radio. It played for approximately 15 minutes, then turned itself off. Only did this one time, so I don't know if this is the norm or not.                                 Joe
