    Dashboard and Component lighting failure

    Going out on a limb here... I noticed that the wiper switch is on the same circuit, and can get lots of use potentially wearing wires and contacts. One day run the wiper switch back and forth through the positions with the headlights (IP lgihts on) and see if the fuse blows then. Most of the...

    Diagnose-No Power/No Air Flowing In Rear Vents

    I my case, I now believe that the solenoids (pictured in the Blower Motor Resistor Assembly) are sticking, or a bad electrical connection. However, I fail to believe that all three solenoids could fail exactly at the same time. If the resistors blew, I'd still get the fan speed on high. It's...

    Popping sound from driver side front.

    I'm getting a popping sound in the same location, mainly on slow sharp turns. I did notice that the upper ball joint squeezed any grease out of the fitting that I put in, so I am suspecting the upper ball joint in my case.

    Diagnose-No Power/No Air Flowing In Rear Vents

    It turns out the post I was looking at was a bit of a red herring: https://www.tahoeyukonforum.com/threads/no-rear-air-at-all.17369/#post-461854 The wiring diagrams in the Chevy FSM are horrible. It took me 3 hours just to sort out and find the relevant connectors and wiring. As far as I can...

    Diagnose-No Power/No Air Flowing In Rear Vents

    Same problem here, I'll be looking into those resistors as well. However I have also read that the orange wire gets burnt at the connector by the parking brake. <-- This is not accurate, at least for 2002. I'll be looking into that as well. I cannot find a wiring diagram in the FSM, but I...

    Towing travel trailor advice

    What Sobro said. And don't waste your money on air lift springs. A WDH will take care of the sag, and handling, especially steering. As for towing capacity, don't forget that the weight of the TT battery, propane, on board water, camping gear etc is not usually included in the dry weight of...

    Oil Cooler Block Off Plate Delete?

    I had no trouble with leaks after changing my block off gasket. I used the ACDelco one, no sealant. There is RTV specifically rated for oil. Also, checking the rear main by looking through the bell housing inspection plate doesn't mean there is no leak from the rear. There is a rear main...

    Coolant leak, can't pinpoint.

    All automotive coolant contains water and ethylene glycol plus a "buffer" to control acidity. As long as the coolant does not become acidic, it won't eat away at the metals in the engine, radiator, thermostat, water pump, etc. As time goes on, a little fresh oxygen always enters the system as...

    Coolant leak, can't pinpoint.

    My first leak at the front was a thermostat housing leak. Replaced gasket, put in new coolant, still leaked. Replaced gasket with coating of thermostat gasket sealant, new coolant again, finally stopped leak. Within a year, water pump leaked. There's lots that can leak up front. Regarding...

    Coolant leak, can't pinpoint.

    A coolant pressure tester was one of the best purchases I made. You hook it up and pressurize the cooling system then look around all over the place for where the leak is. I have found so many leaks this way. Some have said a few leaks don't show until the engine is warm. However, so far I...

    Need Help. 2011 Tahoe cooling system will not pressurize.

    I could be wrong, but I would think if his water pump were that bad he'd have an overheating problem. Pressure is built up mainly by heat, not by the water pump circulating the coolant. When you stop the motor, the system will still remain at 20psi until the system cools. Don't our...

    Need Help. 2011 Tahoe cooling system will not pressurize.

    Have you considered the blend door in the HVAC? If the blend door is stuck on the cold side, your coolant may be up to temperature but the air is not being directed over the heater core, therefore cold air.

    GM lying about fuel rating, or i drive it too hard?

    What part of Canada are you from? Most of Canada is -20°C or lower! (That is -4°F) I don't think GM did their testing at that temperature.

    GM lying about fuel rating, or i drive it too hard?

    How long are you letting it warm up before driving off? First starts are always the hardest on fuel mileage. Colder weather will mean a longer warm up time. If you have any uphill climb first thing in the morning that will more negatively affect your mileage than if your first start is...

    Much better oil pressure after oil change.

    Had you let oil change intervals go for much longer than recommended? Was the oil sludgy when changing? How many miles are on your motor? I have about 200000 miles on my 5.3. I did have a cracked head that allowed a slow coolant leak into the oil. By the time I had to change my oil, it was...

    Unsure if I want Tahoe with AFM

    This is as much as I know about the differences between AFM and DFM. It uses switching lifters like AFM, except there are 8 instead of 4, so this part is multiplied as Chris stated. My knowledge is very fuzzy regarding the oil control, and this part of DFM seems different because it eliminates...

    Unsure if I want Tahoe with AFM

    Actually, Ecoboost blows, quite literally in many ways. So, I wonder if DFM will fare better than AFM? It's relatively new to GM, so any problems won't have cropped up yet, or are just cropping up now I'm sure. Most of you know how to delete AFM, and have done so using several approaches...

    Unsure if I want Tahoe with AFM

    When I looked at all the engine/transmission changes throughout the years along with the efficiency numbers, the biggest changes seemed to come from, in order of most effective to least: 1) 4 speed to 6 speed to 10 speed transmissions 2) direct injection 3) DOD My impressions is that DOD...

    Push button gear selector

    My Tahoe has a neat feature that allows you to start from a stop in 2nd gear. This helps keep traction in slippery conditions. I'm sure I could get used to a push button shifter, but I'm still wishing they'd kept the column shifter, at least as an option. A column shifter would make down...

    Rear glass hinge separated from glass

    3M 5200 for $17: probably works well if done properly. Mine lasted about 2 years. Need really good surface prep. I recall there is a bonding agent available from 3M to promote bonding to old sealant. https://www.canadiantire.ca/en/pdp/3m-marine-adhesive-sealant-5200-white-3-oz-0790215p.html...

    Starter/solenoid for 00 Tahoe 5.3l Vortec

    If you have the skills and patience (stress on the patience) to remove the starter, get yourself a rebuild kit: http://rebuilderinabox.com/ I put in a brand new ACDelco Professional starter and it quit in a week. Not that that will happen to you, but after choosing to rebuild my original one...

    How can I get OEM headlight assembly for cheaper?

    You've got nothing to lose by polishing them yourself. You don't even need a kit, just get a variety of sandpaper, then some polishing compound, and then if you like, some kind of clear coat. If you're "cheap", repolish every few months so you don't have such a big job to do. I polished the...

    Lifters ticking

    You are the 2nd guy I heard from who installed heads ordered from afar and had one crack. The first guy had heads shipped from a shop. I had my heads rebuilt at a local shop that was recommended by a good friend of mine. The main reason I went with a local shop was so that I could go back to...

    Weathertech vs Husky Liners Cargo Liner?

    I have Husky for the cargo area and am happy with it. You can cut holes so you don't have to remove the third row to install the mat. (I'm kind of glad I don't have the 2015 onwards for now. At least I can keep the same cargo mat in with the third row seating.)
