I have had this 2000 Silverado for several years. About a month ago, the remote started not to work unless I was very close to the vehicle...bad battery right?? I replaced the battery (and its in right side up, I checked) and even tried with my second remote that had always worked before...same story. They used to work from about 50 feet away. What's next?

Did you clean the contacts in the remotes when you replaced the batteries? Take a pencil eraser and remove the filmy buildup on the contacts for the battery. Check the batteries for proper voltage using a volt/ohm meter. I've had "new" batteries that were old stock and weak and I had to clean the contacts on my company car remotes to make them work again.

 

Worth a shot.

 

Also... remotes that have gotten damp or wet many times tend to deteriorate. The circuit board inside can corrode. Might make sure they still look fresh. Corrosion makes the electrical pathways see added resistance and will diminish range over time.

:hitit: What Jim said about new batteries being bad and about cleaning the contacts.

 

Another thing is that since these remotes are RF based they are subject to interference that can limit their effective range. I'm not sure what frequency they operate on but things like cell phones, wireless routers, cordless phones, and such can cause interference. I would try using the remote in different locations (eg: home, work, mall, beach, etc) to see if that makes any difference.

Thanks everyone!! I had already cleaned the battery connections, but hadn't thought about cleaning the contacts for the two buttons. I lifted the circuit board out of the housing and found that the contacts were filthy, a little contact cleaner, and a pencil eraser later, and we are back to working at a distance.

Probably a dead horse but...

 

I usually use alcohol (isopropyl) and a shop rag to clean the contacts, especially when there's a filmy, residue on the contacts. Works well on TV remotes as well. Just in case someone else reads this...

      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.

      Electrical Problem - solved

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
