W123, Fuse 8 HVAC
I removed the fuse block so I could re wire The HVAC circuit. Part is melted into the fuse block, not allowing a good connection.
None of the wires are showing signs of cracking or melting. The source is a Red with a yellow stripe. It goes through the fuse, and then to 3 wires, all red with a yellow stripe. Two of the wires are thin, but one is a fat one, even bigger than the source wire. Is the fatter one for the fan? If it is, then I am going to put it on it's own fuse. Thanks!

Well it looks like looking at my wiring diagram. from fuse F8 16amp
1 RD/YL goes to the compressor relay 2.5 RD/YL goes to the Electronic unit for blower speed control .75 RD/YL goes to the Pushbutton control assembly this is from my Electrical Troubleshooting Manual model yr 83 - 85 Charlie

Thanks Charlie!!!
I am assuming the 2.5 wire is the fat one that goes to the fan circuit. Is that right?

The 2.5 wire goes to the Blower Speed Control behind the Glove Box. there are two units side by side behind there. It is for the right one that is a black box. the one to the left, a silver box is the "Electronic unit for temperature control".
I assume you to be right that the 2.5 is the fat wire. It doesn`t say in the manual though. Charlie
