    What's the chance someone could have jumped my Yukon reverse polarity causing damage?

    The bulbs are definitely ok I pulled and checked the with power directly from the battery. I know the relays are working I checked them all.? The odd thing is One Fog connection gets full voltage but I guess not enough amperage to light the bulb the other is getting 0 volts? Oh and I also lost...

    What's the chance someone could have jumped my Yukon reverse polarity causing damage?

    My 01 Yukon was running great until after I left it at my sister's house while moving, I had a Camper I needed to tow with my truck before I could retrieve the Yukon. I just remembered they said the battery died in it and they jumped it to move it. I know my sister didn't but my brother in law...

    2001 GMC Yukon lost Cruise control and Fog lights at re same time??

    Thanks I did put LEDs in the entire vehicle but it was over 10 years ago, had to install resistors. I'll try putting in old school lights as a test but I think it's something else because whatever it is took out the door/hatch open warnings as well? This has me really baffled.

    2001 GMC Yukon lost Cruise control and Fog lights at re same time??

    I'll make this as as short as possible. I went on a long vacation after buying a Ram 2500 Cummins to tow a Fifth Wheel around the country for a year. I put my 01 Yukon in storage in Kentucky for a year. I treated the gas at 1/8 a tank, changed the oil before putting it in storage. Everything...

    I have a old Autel scanner I was going to retire when I purchased an Innova 5160RS, for my other vehicle a 2012 RAM Cummins 2500. I have no issues with it on the RAM but the Yukon I'm seeing 40+ codes that don't make sense (it did recognize the correct vehicle and Year) , O2, MAS , TPS, and...

    (2001 Yukon XL slt) I had a sudden loss of power to both passenger side windows and the sunroof?

It can't be the child lock because it's affecting the sunroof, anyone...

    The last couple days reverse has been acting strange on perfectly flat ground it seems to engage ok but if there's a slight incline very slight it jumps or drops out? The fluid is full and clean the filter was charged about 18 months ago forward is fine at all speeds and inclines. What can I...

    How to protect rear AC lines from salt??? Any ideas?

    I have a gallon of 303 it’s ok but wears off fast especially when it gets wet the lines will sweat when the ac is running I might try wiping pure silicone grease on them. I use it for the door seals and it lasts months.

    Steering issues after 90% rebuild?

    Finally solved it! Apparently the Ford dealership I took it to for a alignment (didn't have a choice everyone else was booked 2 weeks out) left the upper control arm bolts loose or at least they didn't torque them to the required 140 lbs the vehicle called for! I also had 4 loose ball joints (if...

    Steering issues after 90% rebuild?

    I went on my road trip about 8500 miles round trip in 35 days and when I went to rotate the tires I say the cupping on the rear? So I have to idea what’s wrong unless the frame or a suspension part is tweaked Iot was aligning at a dealership they said the alignment was almost perfect before any...

    Steering issues after 90% rebuild?

    Now the tires are feathering on the rear axle? The left more then the right? It’s the inside of the tires the left has probably been damaged beyond repair (at least I cannot just run it on another wheel to flatten it out again) and from what I have read this is from bad shocks? But all 4 shocks...

    Steering issues after 90% rebuild?

    I don't know if the cluster will say anything about it? It's. 2001 was it intigated that far into the ODBII in 2001? But yeah I was going to either unplug the valve on the pump or the Sensor on the steering shaft, and see if it helps? The sensor is more for my year than I expected averaging...

    Steering issues after 90% rebuild?

    That’s a possibility or the unit in the pump? The dealer says it shouldn’t cause this but I may try changing it anyway to see if it makes a difference? Or disable it temporarily to see if the steering behaves?

    Steering issues after 90% rebuild?

    Not yet it seems snug and that wouldn't explain the intermittent issue? There are times when it handles normal? I'm starting to think a cracked frame or something that can shift throwing a wrench into how it's supposed to handle! I looked pretty close but have to find a lift to get it in the...

    Steering issues after 90% rebuild?

    It was disconnected I was changing the CV axle as you can see almost everything is new! I even put a steering stabilizer on it! That made no difference at all so I'm starting to worrie that it might have a cracked frame or something that I don't see yet causing the drift? It sometimes handles...
