Thanks again Hunter! I was having intermittent problems with my A/C and blower so I pulled blower and soldered in new brushes (they were just about gone) and had a short term success of about a day and then lost blower again. I was advised to go to a PNP and find the 30 amp strip fuse aux box and remove as apparently, too much resistance builds up in the lines over time and blown fuses/melted boxes are the rule at this point. I found three of these (very common on 126 car's they are mounted to the firewall near the brake master cylinder) and also a VCV valve along with a uncracked door sill molding for 28.00! I lifted fuse block from fuse box and removed the two screws underneath securing the wires to fuse block, cut off connectors, stripped wired and joined 30 amp leads to each end of the two wires (yellow/red) The mercedes 30 amp aux fuse block holder even has a mount that attaches to firewall for a clean look. I love the way Mercedes allows for mods by having sealed entry points into fuse box so you do not have to drill etc -smart engineering. I hooked up and nothing in spite of the test light affirming current. After 30 minutes of testing etc. I decided to energize blower directly from plug and to my surprise, I forgot that I had unhooked this the other day, ha! Plugged connector in and had immediate blower response! For you 126 owners -this is a repair worth doing that costs almost nothing and is easy on the difficulty scale - a 2 maybe - cool air again, great! It was 102 here yesterday!

can you provide pictures for those of us that are more challenged? ...or visually inspired?

If I can, I will try to take pics this weekend and pretend like I am starting over again -easy enough to do -

question: I keep blowing fuse#1 (which in a 201 is the a/c system.) My condenser fan works, but when it kicks in the 15a fuse blows.

Are you essentially cranking up fuse#1 to 30a or are you removing the condenser fan from the circuit and powering it up on its own 30a circuit?

I guess I would worry about burning wiring. Or am I missing something?

When I scavenged a fuse box from another w201, I found a 25a bayonet fuse in the spares part of the box.

I believe the 30A upgrade is for the evaporator/cabin blower.
