    Hey everyone in Tahoe land! I figured this would be the place to get in the weeds as far as repairs and troubleshooting that YouTube can't supply.
    I'm an union electrician from Portland,OR. I've been sitting home because of the Covid-19 gig going on now!! Strange days!!
    I have a 08 Tahoe LTZ and I removed the stock rear airride shocks with Bilstein 5100" with the Bilstein coil springs and also replaced the front with 5100's. I installed the 50 watt 6 ohm resistor to each rear harness and it worked at first and now I still get the "service suspension system" warning. I did pull the 40 amp fuse for the rear compressor which was blown. Does this fuse also feed the rear shocks?

    Thanks in advance,

    BretM

    Welcome to the forum from Iowa.

    Got a couple folks from Oregon on here.

    Did you put resistors on the front as well?

    I thought the correct ohm value was 3.9? I've been running 3.9 25W resistors on mine for a few months now with no problems.

    Might wanna double check that the harness connections on top of the frame rails right next to the upper rear shock mount bolts are fully and securely connected.

    Welcome to the forum from Oregon


    We recommend that you put all your rig(s) info in your signature so we all don’t have to guess at year, make, model, engine size, trans, rear axle locker…….etc. Makes it way easier on all members that attempt to help, to have that info right up front. It is also recommended that you take a pic of your RPO codes, on the inside cover of the glove box, and post that image in your signature. All this info will greatly help those that will try to help with a problem.


    If there is any other info, like upgrades, mods or recent mechanical/maintenance work done, that would be helpful in any post as well. Too many times a question is asked by the poster and after about 10 responses we find out that the poster has done recent work to attempt to fix the problem or work that was done that SEEMS not related to the problem.

    This is correct... 3.9 ohm 25W or 50W

    Wattage rating makes no difference... the 50W resistors might, potentially, run a little cooler than the 25W.

    Affirmative. And is why I located mine in open air to ensure the cooling fins can work.

    I'd prefer the 50W version. It was a long time ago, but I'm sure the reason I didn't get them was because either I couldn't find them for a good enough price and/or everyone seems to be doing just fine with the 25W ones.

    Hey thanks for the info. I'll source some 3.9 ohm 50w resistors! See what happens.
