    No instrument lighting but other dashboard lights work

    Got it al fixed. I used the led-strip method. Got a 12v LED strip with double sided backing tape on Amazon for about $15. I cut enough of the strip so that I could stick it around the inside of that white cover inside the instrument panel and soldered the end to where one of the lights was on...

    Runs like crap after plug change

    Ok so it turns out it was not the plugs but the wires...more specifically the connection between the wires and the plugs. Long story short the connections on 2 plugs were loose. It was hard to notice...wasn’t arcing or anything...but the wires seemed slightly loose. Basically I just reshaped the...

    Runs like crap after plug change

    I was under the understanding that the only reason they used platinum plugs was for the extra lifespan and that coppers work just fine but need replacing much more frequently.

    Runs like crap after plug change

    can you recommend some cheap copper plugs I can put in temporarily just so I can make sure that is in fact the problem before I buy more plugs?

    Runs like crap after plug change

    The bus has about 200,000 miles on it. I did not clean the MAS and I got the right plug wires for the coils. I have the round coils that part number end in like 2018. scanner does not show misfires unfortunately. I am going to try and isolate the misfiring xylinder(s) with an infrared heat gun...

    Runs like crap after plug change

    THey all, 03 'hoe 5.3 flex... Decided to do some routine maintenance on the beast - plugs, wires, air filter - and afterwards the engine is running like crap, most notably at idle. On the highway the truck seems to have power and is smooth...at idle the engine runs slightly lumpy and...

    No instrument lighting but other dashboard lights work

    Ok so I think I figured it out - all of the lights on the actual instrument cluster light circuit have burned out. I removed and disassembled the cluster and jumped the individual lights with a 9v battery - the turn signals lit right up but the instrument lights did nothing. I then partially...

    No instrument lighting but other dashboard lights work

    Hey all, so I’ve long had an issue with the instrument cluster lights where some areas would we darker than others...and if I tapped on the cluster the sim lights would often brighten. I’ve not driven the truck in a year as I was out of the country, and now I have no instrument lights at all...

    Power seat recline motor drive shaft/cable

    Hey all, so my son was playing with the power seats - reclining the driver seat back and for - and seems to have broke the seat in the process. I found the motor would spin but seat wouldn’t move. I removed the seat and found that the drive cable which goes from the recline-motor to the recline...

    Driver seat recline stuck

    So I managed to bring it up. I got to it by unbolting the seat from the car and tilting the seat backwards. I found a Robinson tip (square head) screw driver but that fit in the hole. I put a socket on the bit and spun it with an air ratchet...slowly the seat started lifting. I am going to leave...

    Ac low side pressure

    Yes, and they are not leaking. The system has held its pressure for a month now without a problem. Just cannot get it cold without driving.

    Ac low side pressure

    I replaced the condenser last summer (along with all the lines, valves, seals, dryer and seals) and it still looks basically new. Shroud is fine.

    Driver seat recline stuck

    Ok, so once I popped the seat cushion up the problem became quite obvious...the shaft that connects the recline motor to the recline mechanism has snapped. I am not sure what these parts are called but it is a small flexible shaft that is spun by the motor. The end which goes into the motor...

    Driver seat recline stuck

    Hello all, Yesterday my son jumped in the driver seat and started playing with buttons and switches and when I went to drive I found the driver seat to be reclined almost fully. When I tried to move it back to normal I could hear the motor running but the seat does not move; the motor runs for...

    Ac low side pressure

    Sorry...thought I had responded to this. So I hooked up the manifold gauge to get the high and low side pressures and this is what I go. Low side pressure was ~50 psi @ 90 degrees (which seems fine) but the high-side pressure is low at ~ 175psi. Not sure what to make of that. I drove through...

    Ac low side pressure

    hey all, So after returning from overseas and preparing the 2003 Hoe for a long road trip I found the AC not functioning. I added 3 cans of r134a which got the condenser running on its own and the truck cooling...but it is not cold. With recirc on the lowest temp I saw was 50f at the vent...

    inner wheel well liner plastic rivets

    Hello all, Not sure if this is the place for this but not sure where else it would go...so I recently replaced all the brake lines in my 03' hoe. In the process I lost/broke all of the plastic rivet/push clips things that hold the inner wheel well liner on. I've tried to find replacements for...

    Front parking brake cable replacement

    Thanks guys. I am not sure that #5 is mounting bolt. I think I can see it but it is too small to be a mounting bolt and seems like it hold the parking brake engagement sensor...but I could be wrong. I can get at the lower #2 nut quite easily but I cannot see the higher one. If I snake my hand...

    Front parking brake cable replacement

    Hey all, I have an 03 Tahoe Z71 with a broken front parking brake cable but I cannot find a writeup or video on how to tackle this. The cable has to attach to the parking brake pedal assembly but I cannot see a way to disconnect the cable from the pedal assembly with it still in the truck. I...
