The BCM is looking for a ground signal on one wire or the other depending on latch position. The link @Fless posted should give you an idea as to how it works.
I would hook up a wire to the negative post of your battery or a known good ground and touch it to each of those wires on the latch one...
I have drained the oil from new compressors and measured to be sure it was the correct amount. You are correct a little more won't hurt but too much could cause slugging and possibly break a belt.
Hard to say. Most of the time when you have a lot of trash on the orifice tube it means the compressor isn't long for the world, or it already crapped the bed... lol
I see what it says but it would seem to me that if the BCM is pushing power to that switch and the switch is connecting it to ground it would be a dead short.
Orifice tube is basically the metering valve and what causes the freon to go from a High pressure/liquid state to a Low pressure/gas state. As the gas expands it gets cold.
The way I read the wiring diagram you shouldn't have voltage at either.
The hood latch is just a simple switch that either connects the purple wire to ground with the latch/hood closed OR provides ground to the pink/black wire when hood/latch is open.
The BCM is looking for a ground signal NOT...
Yeah, I thought about that but figured having something machined to fit with splines inside and out would probably be cost prohibitive.
I ended up going back with just the plain leather wheel and added the "wood" covers on the spokes.
The one I tried to use from a Buick Enclave looks identical except it has wood at the top and bottom. It was physically the same size but for some reason GM decided to change the size of the splined section of the steering shaft to a bigger size on the Buick.
I read this was also the case back...
These trucks use an orifice tube to meter the freon on the front evaporator and an expansion valve to meter the freon on the rear evaporator.
The expansion valve is much more forgiving with low freon pressure than the orifice tube.
I know you mentioned your coolant was low, I am assuming you...

Hope that helps. I contacted one of the GM representatives that used to frequent this forum and had them send me the build sheet for my Burb...
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...
The last one started leaking where the tubes go into the end tank. I'm not 100% sure if those connections are crimped, welded, brazed, epoxied or what???
I did talk to a radiator repair shop about getting the old ones fixed as Cold Case doesn't require them to be returned. He said IF repairable...
I guess I may as well throw my 2 bits in.
I am on my 3rd Cold Case Radiator.
1st one installed 1/1/21 @ 262,225 miles. The brackets on this one had to be trimmed to fit the truck. Started leaking from one of the welds on an end tank. Lasted approximately 2 yrs.
2nd one installed under...
What bags are you using up front?
Are you using the Kelderman air bags in the rear?
If not, what is keeping it from going lower?
The factory air bags for the Trailblazer SS will literally twist into place in the upper crossmember and will allow the frame to lay on the axle if your wheels...
Made it home yesterday about 17:00 (5pm) Eastern time.
Total miles traveled 7,086 miles.
The Burb now has 354,155 miles on her.
I probably should have kept track of the total gallons of gas used so I could get an average for the entire trip but I didn't. I did check the mpg at every fill up and...
I haven't been keeping track of it on the daily. I recorded my starting mileage when we left and have looked at it twice since then. Both times were when I drained my catch can just to see what was what.
1st time I drained approximately 1 Oz at around 3200 miles.
Second time was approximately...
It is doing well. My only real gripe is the fact that they advertise it as a 13" screen and then send you an 11.8" screen according to the sticker that is on the unit. It has a black border around the perimeter of the screen. When I asked if they had inadvertently sent the wrong one they replied...
I think I mentioned it before, but I literally have been praying for months that we would have good weather for our trip, since I knew going at the end of December wasn't exactly optimal.
We chose this time because it was conducive to everyone's schedule, neither my wife nor myself had to miss...
Pikes peak
Day 12 in the bag.
Tomorrow I have nothing, zero, nada planned. Probably just rest and recuperate. We leave for St. Louis early Friday morning heading back home to Florida.
