    Cab light question

    Yes, just pay attention to length of the overall bulb. If it doesn't work simply rotate it as they are polarized. I recommend going with warm white LED's, which doesn't make the interior look pale blue. That's what I have and the light looks like from regular bulb. Avoid "CANBUS" type LEDs...

    Headlights on= No Turns, Headlights off= Turns

    I'd first start checking grounds. That half lit lights indicate that some bulbs get connected in series. Something strange is happening before the circuit even reaches your taillamps. Flashers and brake lights should be separated until you either use a turn signal or turn on hazard lights. In...

    How to flash high beams?

    Thanks, that confirms what I understood from shcematic, however I had hopes that there is a separate circuit responsible just for that which I couldn't find. There is one "headlights" wire coming from the light switch to the dimmer, so when headlights are off there is no power coming to the...

    How to flash high beams?

    I'm installing DRLs and I've realized that I have no idea how to flash high beams with headlights off. With headlights on pulling on the stalk works but I believe every time I pulled it hard enough to switch to high beams and had to switch back, instead of actually flashing them. I'm looking at...

    Cab light question

    Those "ears" doesn't matter, you can replace the ones that have "ears" and flat ends with some stiching out wire with the ones that have no "ears" and pointy ends. Wattage is also not that critical, you won't get a bulb that has more than 10 W. Just make sure that the length is fine

    82 k1500 lost all forward gears no warning signs at all

    More info needed. Which transmission do you have? In '82 a 700R4 was introduced, maybe that's what you have? I'd not even attempt driving as you may burn the clutches in transmission in no time if this is some valve body issue. If you have 700R4 then maybe TV cable snapped. if so do not drive...

    Seat belt retractor

    I had some seatbelt issues a while ago and figured out that these style seatbelts does not react at all to sudden unspooling, they react only to G forces. There is some mystery device between spools that I didn't figured out the purpose, but it doesn't seem to do anything related to sudden...

    Who sells the best fitting dash pad. Time for a new one

    It's a Dash Cover by dashtop.com Part # 206 Someone is selling one in Poland at Marketplace and I wonder if that's the way to go. Price at dashtop is $220.95. Idea of faux leather wrapping my existing dash is growing on me, but that's another topic.

    Wiper Control Module

    You can bypass the module and have no intermittent wipers without any mods. Plugs does fit each other and one of them have some built in attachment points so it doesn't dangle under the column. Did that when I was troubleshooting slow wipers. I did a "relay mod" for my wipers as they were darn...

    getting stuck

    You have no bed? How about adding some ballast, maybe bolt down a piece of concrete? I recall years ago a Nissan Navara where a guy bolted a concrete curb somewhere in the rear to have traction in the winter. Or another Navara guy who carried a layer of pavement concrete tiles in bed

    IS 350 TBI compatible with E10?

    Okay, that's good news for me. E10 gas is currently a big topic in Poland and everyone, including me is probably overreacting :) I recall same commotion when they first introduced gas with biocomponents, now known as E5. However an official page saying that similar engine should not run on E10...

    IS 350 TBI compatible with E10?

    I guess that TBI equivalent of jetting the carb is playing with fuel pressure. Anyway that sounds like making the MPG worse :/

    IS 350 TBI compatible with E10?

    Hi, In Poland in upcoming year we can expect that gas stations will switch from E5 to E10 regular gasoline (95 RON octanes), with E5 most likely available only as premium gas (RON 98 octanes) as gas stations will be mandated to sell E10 gasoline. Is a small block 350 TBI fine with running on...

    Ideas for missing headliner

    The carpet is stiff enough that the area between plywood and side trim is not glued to anything. The glue ends on the edge of the plywood and that couple of centimeters between plywood and plastic trim is self supporting and is not floppy at all. Not shown in the picture are grab handles which...

    gas gauge goes back an forth when im moving.

    Fuel gauges in many cars use some sort of a dampener on a needle, it turns like it is in molasses, I wonder if back in the day gauges had the dampening effect and it simply wore out/dried out? In my 1990 gauge is slightly changing position when accelerating and slowing down, but that's in a...

    Driveshaft vibrations?

    I think I found tiny bit of play in U-joint between transfer case and rear driveshaft. Guys, how to tell which one is needed? Looks like there are couple different sizes that show up in catalogues on Rock Auto and Summit...

    ac control vacume line source

    The diagram should be right for 89 Blazer, ignoring the vacuum modulator for TH400. MAP sensor, etc. should have separate vacuum sources, in form of two tubes going out of throttle body. Vacuum for HVAC and cruise (and transmission) comes out of the separate fitting towards the rear of the...

    Source for 4" backup lights?

    In older pre-CAN vehicles issues with LEDs is related to flashers, not to backup lamps or other lights. Old style flashers use a bimetallic element that needs certain minimum load to operate with long enough interval, when bulb burns out or is replaced with low current drawing LED the interval...

    '87 - 5.7 TBI, Separate Temp Sensor & Sending Unit?

    Bumping this old thread, My oil pressure gauge is always pointing somewhere around 35 PSI, I tested the gauge outside of car and it works OK. So my suspect is an oil pressure sending unit. I'm looking at oil pressure switch/sending unit in my 1990 350 TBI and it appears that the style is...

    Whats you gas mileage on your squarebody truck?

    Next refueling and I got more "typical" gas mileage for a Suburban: 19.7 l/100 km or 12 mpg That's with mixed city/highway driving, traffic jams and me more comfortable with flooring that beast. Fun fact: Clerk was double and triple checking if I do realize that I'm paying for gasoline and not...

    700R4 TV cable - weird adjuster?

    Never seen that style. I'd guess it is some sort of replacement to get it to work. For sure that slop in a TV cable looks concerning! Try opening the throttle all the way and check cable tension, with automatic adjuster it should be under tension. Better to have it too tight and shift late...

    Driveshaft vibrations?

    Thanks guys! For the front driveshaft checking pinion angle is a great suggestion in that other thread. If I can't see any obvious signs of play (other than rotational play which should not result in vibration) in a front driveshaft then maybe that's the issue. Also with front driveshaft I...

    Driveshaft vibrations?

    I think I have driveshaft vibrations from both front and rear driveshaft. Around 55 mph on a clock I start to feel vibration which becomes unpleasant at higher speeds so I drive up to 55 mph. When I drive 55 mph with front hubs engaged, case in 2WD I can feel even more vibrations now coming...
