    Hello folks,

    I have a strange issue/issues that popped up during a road trip this weekend. Everything was working fine, I was humming along the interstate, AC working fine, no warning lights. Stopped at a rest area. When I started back up 15 minutes later, the ABS and BRAKE lights came on, along with the TPMS light (blinking at first, then steady). And along with all of this, the fan/blower didn't work.

    Well, the tire pressures were all good. The brakes seemed to work just fine. But now I hear a clunk-clunk-clunk noise when backing up - seems to come from right front. Totally separate issue?

    So, inquiring minds want to know: WTF?

    All of these things happened/manifested at once after this rest stop, upon restarting. At first I thought maybe a fuse controlled those things? Or maybe it's a function of the ignition switch? And the clunking noise is a separate issues that cropped up at the same time by coincidence?

    Anyway, I'd sure appreciate any guidance!

    TIA,

    Steve

    Noise is only when backing up, not going forward?

    You looked under the truck for anything out of place? Loose wires? ABS wire..?

    Pictures if you find anything weird would help too

    Noise is only when backing up. I looked around underneath and saw nothing loose, but I'll give a closer look later when I can really get under it. Pictures if I find anything suspicious...

    Can't imagine all these issues are related, but idk..

    As far as the HVAC fan goes, does it not work at all, or does it only work on certain speeds (high)?

    Seems like a bunch of disconnected things that could have been percolating for a bit.

    Did your AC fan connector (up under the glove box on the firewall) fry?

    Are your TPMS original? If so, their batteries could/should be done by now. Best bet is to replace all and move on (my state requires all original equipment to be in working order).

    I’d check the brakes and front end components for any play. Do you have a frozen caliper piston? It’s a 12 year old truck after all.

    Are you lifted? What kind of wheels? How are the U-joints?

    Good luck. Keep us posted.

    Thanks all for your feedback. I feel like the clunk-clunk-clunk in reverse (and it doesn't happen every time) is separate from the others. I did a search before I posted here, and the only similar incident I came up with was on a Chevy Trailblazer! The guy had his ABS and BRAKE lights come on when he started up, AND the blower didn't work. Turned out to be the ignition switch (ignition control module) - that's why I mentioned it in my OP. Is such a thing possible in Tacoma-land?

    1.First thing you need to do is check for codes 2. Check fuses - hood and cabin, especially the IG1 2 fuse 3. Jack up rear and front to hand spin tires to check for noises and play. 4. Pull tires to inspect brakes and for leaks.

    As for the blower, get out a voltmeter to check 12V at the connector with ign on or direct connect the blower to the battery to see if it kicks on.

    Just an FYI, an ignition switch and ignition control module are not the same unit. The 2nd Gen doesn't have a separate ICM. It's controlled through the ECU and typically if it fails, you will know along with with a CEL. I doubt it's either unit.

    It was in fact the IG1 No. 2 fuse. Replacing it fixed everything. Not sure why it blew - but everything has been good now for a couple of days.

    Thanks for all the suggestions!
