Chevy - GMC Chassis / Re: Hazard and Brake Lights Sw...

Last post by eXodus - Yesterday at 05:11 AM

All I can say is if the original circuit is like the ones in the drawings, then at the Brake Light switch the three post portion should be the portion your looking for with the following three wires in that three post connector:

Orange (circuit 140) from fuse
Blue (Circuit 20) for 3rd brake light (isolated from hazard switch when brake is resting)
White (Circuit 17) for turn signal switch, cruise control, etc.

I've  moved the brake controller from the White to the Blue wire at Paddle switch and it seems like to behave like you are describing. No Pulsing on Blue for the 3rd Brake light (I don't have one - anyhow)

So there was simple solution for the problem

Project Blogs / Pantry Pull replacement for a ...

Last post by grhoades - February 05, 2023, 04:54 PM

Hello, this is my first post so I hope I am in the right place.  My wife and I are replacing all the drawer and cabinet pulls with ones my wife prefers.  We got to the vertical pantry pull outs are are stumped.  The screws for the handle are not accessible from the inside.  We believe the fron of the cabinet comes off to access the screws.  There are screws down the front side that hold the front on, but nothing on the back side.

Does anyone know how to remove the pantry front to access the handle screws?

Thank you for the help.

All good

I've just added the Thermostat-switch to the Wiring Diagram which I have been using for the final diagnosis.

Might help someone in the Future.  But how the A/C system works - the manufacturer could have put the thermostat in series with any of the other switches and achieve the same effect- shut it down when getting to cold.

Just a safety device to prevent the condenser from freezing up. Most likely added by RV Mfg.

I made a description mistake - its the evaporator housing and not the condenser - the evaporator is the thing which is getting cold - the condenser is warm.

Thanks Dave.

I've ordered the part and should get it in week or two.  I found video how to replace it with minimum effort - might be not as accurate placed as before. but good enough to act as a safety device.

Hi! New here. I have the same exact rig and same problem. Can anyone tell me if the fuel pump is inside the tank, on top of the tank, or in the front of the engine? Really don't want to have to drop the tank if I don't have to. Tell me somethjn' good! Any manuals available?

First you are posting in the Oshkosh (John Deere) chassis with a Ford 460 engine area however your bio says you have a Chevy P30 chassis with a 454.  2 different chassis Mfg's with different implementations.  Need to verify whether you have a Oshkosh or Chevy chassis first.

What does this thermostat do? It is not part of any electric drawing I could find.

Think in terms of a glass of ice water where condensation builds up on the outside of the glass (warm air on cold surface).
If the condenser temp gets below 32F (0C) then ice starts to form.  The thermo-relay detects the low temp (31F) and opens the circuit shutting down the AC.  Once the condenser temp gets back up to around 39F it closes allowing the AC to turn back ON.  Just a safety device to prevent the condenser from freezing up. Most likely added by RV Mfg.

After lots of crawling under the dash tracing wires and in the engine bay I finally found component which is causing my troubles.
There is a small component on top of the airbox where the condenser lives.  It gets the 12V from the dash A/C control and then from there it goes to the High pressure switch at the back of the compressor.

The wire going to the "thing" had a weathered label with a printed "AC sense"  on it.  It only has two electric connectors attached.  I've bridge them with a 5A fuse and my A/C running nice again.

It has thin metal pipe attached and when I look up the parts number it says it's a

a46-3122-000 thermostat. Which is now superseded by A46-3122-030
https://www.ebay.com/itm/112336927082

It's $45 and I looks like the sense tube is going into the condenser housing and will be a pain to replace.

What does this thermostat do? It is not part of any electric drawing I could find.

The only reference I could find someone in https://www.rvforum.net/threads/whats-this-ac-part-called.56040/  saying it's against freezing up. I'm in Florida and never drive in cold weather. Is this necessary?

yeah well, maybe you really are driving too fast. Rv's are driving bricks after all.   

In America you are experiencing fuelprices like they were in Europe back then, So maybe next thread will change you mind

Just as a tip of course, but with fuelprices as they are nowadays,,,,,
