So as some might know from recent posts that I've had a lingering issue with my heated seats coming on then cutting out. Dealer replaced a circuit breaker but didn't correct the problem. So was going to take back for another attempt at solving when I had time

 

OK, its my understanding that the seat heater and adjustable pedals share the same circuit. So last weekend my wife and I are on our way back from an out of town football game and she has been using the heater but like usual they are cutting off at random times. Anyway while motoring down the highway at 70 mph at 9:00 at night this guy for some reason decides to pull out in front of us from a cross road. The distance was like -100 feet so with someone on my right side all I could do was apply the brakes and fairly hard. The truck preformed great at slowing down and thank goodness that idiot had enough since to gas it.

 

After that the seat heaters have worked flawlessly ... :banghead: ... so what the heck did slamming on the brakes at 70 mph have to do with fixing my seat heaters?

I had a 64 Impala that wouldn't start unless the windshield wipers were cycled. Turned out the wiper motor flexed the firewall to seat the bulkhead connector and make contact. You probably have a loose wire or connector.

Do you have adjustable pedals?

 

Yes and not to sure on the loose connector. There is actually an older Service Bulletin that refers to the heat seats cutting out after approx. 30 seconds.

That is what I was getting at and I missed the part in the first post where you said you did have them. They share a 5v reference like the bulliten says. If there is an issue at the sensor that is pulling the circuit low slamming the brakes could jar it enough to make it ok for the time being. Of course when you slam on the brakes there is alot of force on the whole vehicle that isn't usually there so any poor connection could have went good as a result. Knowing that the adjustable pedals share a circuit and that you were slamming your foot in that area makes it a good place to start.

That makes a lot more sense for sure and will point it out to the dealer if the issue shows back up ... thanks! Wonder exactly where that sensor is located at?

    • I like the idea.  I would pick diesel if I had a choice. I need pictures though.
    • I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

    • You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode. 
    • "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
