Ha! No way, I will try that, thank you so much!

So I am absolutely confused on this issue. I have ordered a new blower control switch (for behind the dash panel) and a new connector (in case of mine being melted) on the advice of many of you above. I have read up on adding relays around the connection at the resistor to assist in managing electric flow in the future, and had ordered parts to begin that modification. I went to work on replacing said parts above, tested the air one final time before opening up the dash, and it works! What is happening that would cause unpredictable electric current to components some days, and no current on other days. There appears to be no correlation between temperature as I am in south FL....

So, as-is I should be able to turn the key and have air on low? Please forgive me, when I said relay I meant resistor. I replaced the small rectangle piece under the passenger dash with the coiled metal design.

I didn’t think the melted parts were affecting the metal connectors. I will re-inspect in the morning and report back.

This is where I’m at. Am I close?

I can try this tomorrow, can you elaborate on what to do exactly? I am very new to electrical issues in vehicles and am having trouble with some of your terms. Thank you in advance!

I replaced the resistor when I replaced the blower motor. Everything seems to be good down there.

Just checking in with everyone: Some random tinkering under the hood and my blower motor started working again. I assumed we had a loose electrical connection. Fan speed switch is functional, and hose is connected to the top of the engine. Added the additional ground for the blower motor per crusier54's direction. I assumed all was well. Blower motor cut off while driving and no amount of jiggling the connection will make it respond. Any new ideas? Fuses are unbroken. It appears to be a bad electrical somewhere...

I started to work through your tip #1 to refresh the grounds and saw this! I am looking to make this adjustment this weekend; do you have advice on the wire gauge eyelet to get? This is the item I was going to order: https://www.mcmaster.com/electrical-connectors/ring-terminals/insulated-high-temperature-ring-terminals/ Additionally, I lost the grounding screw on the driver front end inner that you refer to in tip #1 and borrowed one from another location to fill the void. Do you happen to know the screw size? I was going to guess and order an M6 x 1 mm Thread, 20 mm Long but wanted to make sure. THANK YOU in advance :)

I plan to check these this weekend, thank you both!

Okay friends, air has functioned properly for the day, and all of a sudden quit working just as before. Brand new blower motor and brand new relay. Checked fuses and both are intact. There must be a short or something wrong with the electrical. What now??

Am I reading this correct that it should be left the way it is? I could not locate a place to plug in. Thanks everyone for the feedback!

Okay guys, thanks for the feedback! I changed the blower motor and the relay and seem to have solved the problem! Found a vacuum hose that was not connected, however. Anyone know where this goes?

My air conditioning unit worked well and blew cold air, and suddenly shut off in the middle of driving. No setting works, and the fuses in the box and under the hood all appear unbroken. Any ideas?

@Eagle nailed it! The ground was bad! Found a local shop in TPA called Red Scorpion Fabworks that fixed it for me for $50 out the door. Thank you all for your time and feedback!
