My 99 Tahoe is having some intermittent problems... I am not sure if they could be related to the alarm, a Viper with remote start, paging, etc, or some other problem. Upon turning off the truck, the HVAC blower will continue to run. Also my compass/temp/computer module from a Blazer I installed will also remain on, without the key. Turning the blower off and on does not change the condition. Jiggling the ignition lock does nothing ( I thought of the ignition switch at first) .Nothing else works, the radio, wipers, turn signals, etc that are powered normally with the key in accessory or run function.

I know I can remote start my turck, and if I have the AC and blower set to on, it will run the blower, but nothing else. I assume that function is controled by the alarm module, and ultimately relays. Could the alarm cause this? Bad electronics? Bad relays?

 

Just your thoughts, please.

 

Thanks,

John

I don't know if this is your problem but I had a Blower Motor Resistor Pack fain on a Chevy Express and it left the fan on ALWAYS until the battery died. Didn't matter whether or not the key was in. Replacing the resistor pack cured the problem.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.
