    I installed E-fans on my 2001

    I see what you're saying about constantly cycling when the AC clutch is engaged. And yes, I can confirm that DOES indeed happen, because my fans are wired to the AC clutch. In colder or extremely humid weather when I have the defroster running, I can hear my fans CONSTANTLY kicking on and off...

    Electric Fan Conversion Question

    You are WAY overthinking all of this. Are you really willing to sacrifice you AC circulation function JUST to have the PCM trigger the fans, and not the AC compressor trigger the fans? Yes, the temp relay commands them on at low speed. But low speed is more than enough to cool just fine in...

    '02 Loose Shifter

    If you have a loud stereo system with big subwoofers, the constant vibrations can cause bolts to come loose. I had that problem with the steering column on a Cutlass that I used to own. I had three 10" subs on a big Kicker amp beating up rhe block knocking pictures of the walls. The screws in...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    I dont understand why so many people hack up their floors like this. Some people do it because they buy cheaper pumps that fail every 2-3 years, and they want it easier to replace. To each his own, I guess. When my fuel pump went out, I just forked out the cash for an OEM AC Delco fuel pump...

    Electric Fan Conversion Question

    I remember reading in a thread over on Performance Trucks about adding a pressure sensor and then reconfigure the computer software to recognize it and everything. So it can allegedly be done, but in my opinion it's not worth the hassle. Like I said, I have been daily driving my 2001 like...

    Electric Fan Conversion Question

    In most climates, it would be just fine. But in very humid climates, like here in Louisiana, the AC compressor comes on to help the defroster to decrease humidity, and it that actually helps a LOT. But in drier climates, you will most likely not see any issue. Another option would be to wire...

    Electric Fan Conversion Question

    Yes, the extra relay I added in the harness is needed to convert the AC compressor clutch trigger wire to work with the fan harness. And yes, its a pretty tight fit under the fuse block stuffing the harness and relay underneath the fuse block, but it just BARELY fits. On the 00-02 trucks, there...

    What % window tint do y'all have ?

    This is exactly what I have on my rig. Abd I have NEVER been pulled over for my window tint. I've had other cars in the past that had 20% tint all the way around, and I have been pulled over several times because of the tint. But in the 19 years I have been driving my Suburban, not one single time.

    Brake light on and wires frayed??

    That looks like rodent damage. Plus a lot of those wires are already corroded. To repair it properly, you will need to cut out all the corroded sections till you can see bright clean copper again, then solder a repair section in. It will be very time consuming, but if you can solder, it should...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Correct. I've had to repair broken wires inside the rubber door jamb boot. Due to the flexing of the door opening and closing, I had two wires that broke. One was a door lock wire, and one was a speaker wire. But the complete wire wasn't broken, just the conductors. The insulation was still...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    Worst case scenario, if you can't repair that wire. You could always go cut that plug off a donor truck in the junkyard, and just splice every wire in that harness. That's what I did when I had a bad wire in the plug for my power windows.

    Parking Brakes Need Replaced

    To give you an idea how long parking brake shoes will last the average person, I'll share my experience with my 2001. I bought my right in 2005, so I'm assuming everything was all original. In about 2009, I replaced the rear brakes, and just adjusted the tension on the parking brake shoes...

    Electric Fan Conversion Question

    Yeah, I sell just the harness and relay block. The whole plastic cover is something completely separate. But on my 2001, everything fits under my stock cover. The only drawback is there's no access cover to access the relays and fuses. If I need to access them, I have to unblock the fender...

    OEM GMT800/NBS Electric Fan Harnesses For Sale

    Correct. It basically clips right onto the stock fuse block, and it fits under the stock fuse block cover. OR....You could also swap over to the 05-06 fuse block cover, and that one actually has an access cover to gain access to the cooling fan relays. Otherwise, you need to pull the whole...

    Can't find the source of this whining sound

    Definitely a bearing on one of the pulleys screaming. Its most likely the idler pulley or belt tensioner. But it could also be ANY belt driven pulley, so check them all. If you have a Harbor Freight near you, go buy a "Mechanic's Stethoscope". They ate under 10 bucks and are super useful in...

    Neither, I actually meant to type "damage". But mangle also works as a descriptive word. Lol!

    New Cluster Needed?

    https://www.tahoeyukonforum.com/threads/how-to-replacing-03-06-nbs-instrument-cluster-stepper-motors.42521/ Here's an instructional thread I made on replacing the stepper motors. As long as nobody has been messing around soldering in it prior to you, then it's fairly easy, especially if you...

    New Cluster Needed?

    I've rebuilt quite a few 03-06 clusters, along with adding LED backlighting. I've done a few for some members on here actually. Done plenty of LED backlogs in AC controls and headlight switches and door switches, etc. But I have gotten away from it because it's SO time consuming to do. And...

    Front marker light wiring question

    The parking light wire should be a brown wire. On my 2001 it is, at least. Perhaps it might be purple or blue on a 2003-2006.

    Location for analog oil pressure gauge plug

    Yes, it is. I connected to that port on mine without moving the power steering pump or bracket. I can't remember EXACTLY, (it's been a few years since I did this) but l believe I had to use a Flex head ratchet or something. All I remember was the 8mm bit socket on a regular ratchet would not...

    2003 Yukon XL 4x4 Pop clunk issue

    Sounds like it could be the spider gears in the rear diff. Do like Scottydoggs suggested and check it out to see if it's in the rear end.
