Heating and Ventilation

I am looking for TSB 89501, which covers retrofitting R12 AC systems with R134a. 

My question is with my 1985.5 944.

My a/c blows cold, but when I turn, or speedup or slowdown, it stops blowing cold and it seems like the fan is working harder.  Could I have water somewhere that is affecting the fan motor?

The air conditioning works ok, but when I turn, speed up or slow down it stops blowing cold air, and the fan motor seems to work harder.  Could I have water somewhere that is affecting the blower?

The problem is with my A/C in my 1983 944.  I have owned the car since new and I had the freon checked and added new freon at the end of last summer (this was done by an A/C shop).  My problem is the A/C will not come on when I turn the A/C on.  The vast majority of the time it will come on after I have driven the car a few minutes.  After that it works great. Occaisionally it will come on right away but not very often.  I searched the questions on PCA and I did not find an answer to my problem.

My 1983 944 heater / defroster blower suddenly stopped working. It doesn't work at any speed so I am thinking not a resistor problem. What's next? Relay?

How do you change the heater blower motor resistors? I have lost the medium speed.

I recently had to tear apart my dash to have the AC evaporator replaced. The harness behind the climate control unit came apart and scattered wires. I tried to replace them correctly put it is not behaving 100% correctly. Do you have a wiring diagram that shows the correct wire color for each pin location on the three harness connectors?
