Whacky Locks!

My 2006 Taco has gone crazy. The keyless entry system locks and unlocks at will. This can go on for hours and the hazard lights flash when the locks stop engaging. Finally had to disconnect the battery. Truck has 90K on it and I am the original owner It has been flawless to the point. Anyone ever experience this?

 

I had similar problems with my last tacoma. I traced it back to a replacement windshield...I guess it wasn't sealed well and after it rained water would drip onto the fuse box and cause all kinds of wacky things. I mentioned it to a couple of dudes I know and one had a similar problem because the weep holes at the bottom of the windshield under the hood outside the firewall were clogged up with leaves and such. Don't know if this is your problem but something to check out. Also one my wife old Saab (don't get me started on this one) when the battery was running low on the alarm it would go off randomly.

 

Traded in a 2000 9-5 for my Tacoma. Dont get me started on the random alarm thing... happened to me all the time. I tried everything I could, including breaking open the alarm box and soldering in a new battery. I eventually had my mechanic totally disable the damn thing. That was one of only a handful of problems though, I was lucky and got a pretty good one. Kinda miss her, she was my first car! As for the OPs issue, the only thing I can think of (other than water in the electronics) is a faulty/low battery in your key fob. On some cars it is known to cause some wacky behavior. Good luck!

 

Have you done any mods recently ? Might want to look at those and no it doesn't matter if it was not an electric related mod. Random wires pierced/broken/pulled partially out/loosened via drill bit, screw, moving out of the way etc can cause issues. Check batt charge / water in cells and terminals then if you dont find it well its down to chasing harnesses and connectors to fine loose connectors or burnt/melted/chaffed wires some where.

Funny story when I worked RF-4Cs had one that with auto pilot engaged above 14k Alt or so would do an un-commanded left slow roll. The sparkys and and bubble chasers along with the black box geeks chased that prob for 3 months. They damn near rewired every connector and ground on the plane. Come to find out after a de-panel party from cockpit down to the wings and wire chase and physically check clamps and bulk head pass through .... Tada a wire for the aileron / flap controls ( been to long can’t remember which so don’t call me on it) was chaffed you could see the rub marks on the insulation and the adel clamp. The bare spot would contact the clamp at altitude do to the contraction of the wire from cold. Hence they could never reproduce it on the ground lol Moral of the story weird shit happens ..
