OK so I bought an 07 tahoe ltz, it has the button for heated washer fluid. When I press it nothing happens, I have read that it was on a tsb. Honestly I have not looked if it's a fuse,cut wires with electrical tape,I don't even know where to look?
Either way I probably won't even use it but I would like it to work. Any pointers would be great thanks.

It was a 'feature' that turned into a fire hazard defect and was disabled by GM.

Harness with fuse if you decide to keep it...
But as others have said, there is a fire risk.. be especially careful when low on washer fluid, don't want to run dry.


Kia version of heater in case they removed your heater altogether..
Hopefully the fire hazard has been addressed.. I don't see any recall for Kia/Hyundai heaters?
(What I am using currently, there is less wiring and it activates everytime the truck is started)


Another heater I purchased in case the kia/hyundai heater dies, which looks to have more capacity..

There was a recall on them and GM issued a $100 check when you brought it into the dealership to have it disabled.

My '08 had it done by the first owner so they got the cash and I got what was left of the system... lol

On mine they simply cut the wires and taped them up and I think removed a fuse if my memory serves.

I live in Florida and don't really care about heated washer fluid so I repurposed the switch using a latching relay and the existing wiring to control a light bar originally, now it has been repurposed as an activation switch for my train horn.

The cut wires should be on the firewall on the driver's side between the brake booster and the driver's fender.

Thanks for the location, I'm not entirely sure but I can use the wiring and factory switch, I mean it's there so why not. Any idea on the fuse location? Thanks

What are you not understanding here... This feature was deemed unsafe by GM and they decided to disable the system completely for safety reasons. There is no reason at all to reactivate it, only to endanger yourself, your property, or even other people when / if it causes a fire? If having the heated button causes you to feel you need it to work, just remove that switch panel and install one from an 09 and up that doesn't have the heated switch

I thought the OP was wanting to repurpose that button for something else, like I did to control my light bar, and then later to control my train horn.

Obviously hooking the heater back up would be ill advised.

I personally just hate having a perfectly good button there that does nothing, which is why I figured out the wiring and repurposed it for something else.

I know there are aftermarket heaters for the washer fluid but I'm not sure if they are any better/safer than OEM.

That makes sense to me ;)

They are just warning of the fire hazard...
Which HAS burned some member's cars to the ground!
And when you see a photo of a completely burned vehicle, it's worrisome.

That said, I'm still running one...
I can only pray that changes in Kia/Hyundai versions will hopefully prevent a meltdown.
There are plenty of electric heaters in cars that don't start a fire, so I don't think it should have been difficult to fix... if they cared.

Which reminds me, I need to mount a fire extinguisher somewheres.

I caught rude as soon as I read what don't you understand. Either way if not I apologize. The more I read I would like it to function properly. Even if using an aftermarket pump. Honestly depending who was tapeing the wires may cause a worse fire Hazzard?? Anyway i digress but would like any advice on making it work, oe,aftermarket, Kia don't really care.
Not concerned on opinions of if should or should not,, plenty have it plenty replaced with different sources and have successfully done it.
I was going to repourpose the switch but it has gotten cold.why not make it work correctly not taped wires and such?
Thanks all

I don't care if you hook it up or not. just lived in a warm state my whole life. I hate the cold, especially because I'm usually work. outside.

I thought windshield washer fluid didn't freeze to like neg 30F. what's the warmer doing?

Supposed to help thaw the ice on your windshield.

With the summer blend being the only thing sold around here, it's good to 32deg.
I struggled with it only once on a roadtrip, but I don't want it to ever happen again!

That said, I think my KIA/Hyundai washer quit working.. It doesn't steam like it did before...
Maybe it's not cold enough? (They may have lowered the temperature from the original used by GM also)

Think I'm going to try this Delphi heater I have. I'm hoping it's larger capacity and more heat...
I need to have a switch/relay for it, so it doesn't heat up everytime I start the car.. that can't be good for longevity..

Kia/Hyundai (Alphatherm AT-38OD or Donmar Hotshot RDX) has a thermostat, and is voltage sensing.
Temp listed at 125-135 degrees. 60A fuse, can hook directly to battery. Mine was apparently from a kit for 2013 Hyundai Santa Fe..
Wait upto 30 seconds before first 3 second spray. (Enough hot water for about 2 seconds of spray..) then you have to wait ~20 seconds for it to heat up again.
Instructions mention that if the heater is dropped, it may cease to function. So I guess it's sort of fragile..

Delphi HTK200 heater is also voltage sensing (13.2V). BUT it has a separate ignition turn on wire, so I won't need a relay to switch it!
Output temp listed at ~140 degrees. 100A fuse.
Wiring pokes right out of the case, no waterproof connectors, mount consists of a giant hose clamp.
Says to wait only 10 seconds before first spray, 3-5 seconds bursts waiting only 5 seconds between bursts.
Instructions state 'for commercial vehicles'. Must draw more juice.. no specs.
