I ordered an AC Delco D1954F to replace the switch in my 2012 2500hd LS (upgraded work truck)...I asked this question a while ago, got an answer, and for the life of me I can't get the search to work now.

 

I have a crew cab, power/heated mirrors...again, essentially a WT.

 

Before I get and try to install it, is this the correct switch? I had to order a gas cap because I'm getting the "small evap leak" code, and threw this switch on the Rock Auto order.

Switch installed, works perfectly...same switch I took out (every marking and tag was the same).

I watched a video on how to swap them out, and one of the comments stated "clean the contacts before replacing". What? Having already swapped the non-working for working switch, what harm can come from experimenting. The switch body snaps together, so using a flat plastic trim pry bar, I popped it apart. The finger pieces of the switch come out with the top, there is a silicone rubber gasket that contains the upper part of the "switch" or contacts and then the body with the circuit board and other half of the contact. Mine were blacken, either from dirt or arcing. A little light scratching with a knife and everything is clean again...keep in mind these contacts are about 1/4" in diameter and thin, so you go easy. Do both the contact in the silicone rubber and the circuit board, slide things back together, snap it together, and done...that switch now works fine (plugged it in to check). I don't know how long that fix would last, but to get you by for a spell or to give you a spare; it's worth the five minutes to clean those contacts.

Here is what it looks like apart...I find it funny there are LEDs in here and my switches don't illuminate.

Contacts that get dirty...all those little gold dots that are about 1/4" in diameter are the contacts. It will be quite obvious when you first take it apart which one is giving g you issues because they will look dirty; the less used switches will have clean contacts.

I used a knife blade and carefully scratched the "dirt" off each contact. Assembly is the reverse of disassembly, there is one duck-bill looking piece that sits on the silicone rubber that is indexed in two small holes, make sure you don't drop that, it's really the only loose piece in here.7323ef24f208f3ab654e6a8e00083b59.jpgbc329e63e9c59b4c908bd5ecfadcc919.jpg1d6afddbd7c258a1b28363795978ad3d.jpg

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
