Taking off the dog house. With mine , I slide the seats back as far as I can. Lift the mounting brackets at the bottom of the dog house. Fold them up. Then move the dog house as far back on the floor as possible. Up against the seats. Now tilt the top of the dog house back . It should just barely clear the dash. It should be now clear and able to pull out of the van. That broken ground strap goes from the block to the transmission . Fix that. Clean the negative terminal up front where it bolts to the block . Mounts low on front of engine near crank pully. There's also small ground wires near headlights. Clean all grounds and mounting surfaces. Wire brush or sandpaper. I add dialectic grease to ground terminals , prevents corrosion.
I've been there on my G-20. Get a new in-line check valve. You had one when you pulled the vacuum line off the block. Check or just replace the vacuum line going to the vacuum reservoir ( round ball attached to hood. ) When the vacuum line is cracked or disconnected it effects the A/C system ( like you fixed ) and can effect your engine idle. Good job fellas.
❤❤❤ this, Ty I have a 92 Chevy G30 Sport van. I cannot get anyone to help me answer any two questions. Your controls are exactly like mine. The Ac/heater slide controls. 1 question the two control knobs on the top. The right one has a two prongs 1has a blu wire attached, the other is empty. The wire that is attached looks like a small shape blu wire that I am wondering connects to the left knob???? Any Idea? Now the left knob has 5 prongs all are attached except 1. Which I was thinking the u shaped blu wire piggy backs to. Now that's just the knob will send you pictures. From a a group of wires all band together, a bit lower there is only 1 wire not attached to anything which I was thinking goes to the second prong on right side knob that is empty?? Any Ideas??
It could be. Iv never messed with them before but the spees controls are worked off of a register. So if HI works but low or medium doesn't, then you have a bad resistor pack
