What Have You Done To Your 2nd Gen Tacoma Today?

It must be pretty trick/intricate. ABS is super easy to form and for it to require a CNC it's gotta be trick.

 

Morning from Alberta everyone.

First post, so I'll start with the positive than jump right into the negative.

Ready for some northern canada exploring once this cold weather frigs off. Rigs prepped and ready for another adventure.

However, for the negative... My driver side heated seat has stopped working. Light still turns on, passenger side works fine but no heat on driver. Multimeter shows 3.6 ohms when I test harness.

Any ideas on this fix?

 

It requires a few things done to it that a simple forming wouldn't accomplish. Will be posting a dedicated thread about it once I get a working prototype in but will also post some pics in here .

 

I love fabricating new ideas. I'm looking forward to seeing what you come up with.

 

I'm pretty excited about it. Its been in the works for a few weeks now and its killing me that I cant post much about it just yet. It's so close! The reveal will be soon. I think it will be a great product. It was originally just going to be a one off thing to solve an issue I had and some of my buddies with tacomas saw/heard about it and were asking if I could make one for them too so then decided what the heck, may as well make them professionally and see if everyone on here had some interest. I'm hoping to get my prototype by the end of this week and if everything goes accordingly then I'll be able to start a thread on it.

 

Yeah I’m personally super stoked and looking forward to seeing the big release. This is all going to help me tremendously in outfitting my truck so that I can finally have the needed storage to make some extended camping trips with my daughter.

The timing couldn’t have worked out better when combined with the Alu-Cab group buy that I just informed everyone of over on the GB thread.

 

Couple questions.

1. Test the input and output of the other seat heater, do you get the same resistance?

2. You have resistance, I’m assuming you have continuity, but I assume and then I feel dumb for assuming.

3. Do you get 12 volts to the seat end of the harness when the switch is on? Maybe you have a breach in the power supply to the heater but the heater element itself is fine.

 

They snap into the headrest mounts. Smart phone holders for the rear pass - kids for trips

 

1. Same resistance

2. My dumbarse should've tested continuity prior to posting. 12 volts to the seat end of harness on passenger side. 0 to the driver side. Must have a breach.

Not too sure where to go from here?

(Mechanically I'm alright, electrically that's a different story... any help is greatly appreciated).

 

The first place I'd look at is the owners manual for the truck or the underside of the fuse box cover to find out if the driver and passenger seat heaters use a separate fuse. If they're separate fuses check the fuse for the driver's side. The second place I'd look is actually the same place, I'd be looking to find out if the factory seat heaters use seperate relays which would also be in the fuse box. If the fuse(s?) and relays (?) are good then there is a breach in the wire somewhere.

To look for a breach I would first find out what aftermarket accessories are on the vehicle. If anything is mounted to the floor that's where I'd look first. Then I would see what electrically those aftermarket accessories were attached to. Next I'd follow/trace out the harness that the heater wires are in and when I came across a plug I would unplug it and look at both sides of the connection terminals. After that first plug it'll probably be very difficult to trace and a wiring diagram would probably be needed.

I would also check the resistance to ground on the seat heater with it unplugged because even if it shows the correct resistance within itself that doesn't mean that it doesn't have a short to ground inside the seat.

 

RE: ideas on seat heater not working

Maybe wear pants?

(Sorry, couldn't resist!)

 

good to know thanks!

 

Bobbing is going well I see!

 

Taking off all skids. Working on fitting my skids plates perfectly together and changing hardware. Doing some grinding and cutting. Lol.

 

Good riddance!

 

@61FunGun I assume you checked the fuse. Did you compare that resistance measurement with the other seat?

If the fuse is good and the resistances are close, I'd swap the switch.

I don't have the factory heated seats so I'm not totally familiar with their wiring for it

The ones I installed in my truck, have a variable control vs high/low. The variable switch, if you have it, could be the issue.

Edit. Compare voltages between the seats as well. If you can do that with everything plugged in, even better.

 

3.6 ohms to both driver and passenger.

12 volts to passenger. 0 to driver.

Fuse is good.

Going to try swapping the switch and see what happens!

 

If that doesn't work, listen for a relay clicking when you turn on the working seat. Could be that as well.

 

Today..........

 

As I'm bouncing between here and my truck... I've been plagued with an intermittent P0333 code.

I got my inspection camera all set up. And I'm underneath, looking up and happen to see 2 connectors. One of which, looks very much like the replacement knock sensor harness.

Funny, it doesn't look like it's plugged in all the way... Surprise! The mechanic who swapped motors for me broke the locking tab.

Tyrap to the rescue.
I'll be psyched if the code goes away though.


Shit like this is why I do everything I can and some stuff I probably shouldn't. Lol
