Well, regardless of what happens here, I still wanna know where that HVAC programmer is!! Is it part of the climate control, or under the dash on the passenger side, or just where is it??

Well, on my 96 the HVAC Programmer is located on the passenger side of the HVAC aasembly, mounted vertically in behind the glovebox and dash bracing. You can see the bottom of it if you get your head stuck under the dash--it'* a black box about 3in x 6in x 10in and it has all these colored vacuum hoses connected to it at the bottom.

I had to pull mine out in order to replace the air mix door actuator (a $35 part BTW)--just so you've been warned, step one of the replacement procedure is remove the dash--not a activity for the faint of heart--took me about 5 hours start to finish

of course, the 93 may be different--I don't know for sure

I also just replaced the air mix door actuator. If you check the post"AC blowing hot air" Uri sent some pictures of the dash apart. The programer is not shown but it sits up under the dash on the right of hvac assembly and is held on with 2 screws, but you cannot pull it down until you unplug the small connector to the actuator.
I think I would start by testing the blower motor with a direct connection or on the bench as others have mentioned.

You need a multimeter to test the voltage at the blower fan when it is commanded at the highest setting. I would not change out the programmer because it is expensive, and the fan speed is also controlled by the blower control module. There is no resistor pack with the electronic climate control.

I am fairly sure that the programmer and control head communicate via a data line. If the system performs other functions properly, I would bet you that your problem is the blower control module or the fan motor itself.

FYI, when you put a different radio into a 93 SSE/SSEi you have to follow this procedure. I suspect you have already lost the dimming capability of the VF display on the control head.

Okay, I put a volt meter on the wire, turned it on...nothing. I found the ohter fuse block on the passenger side that he was talking about and found the 10 amp fuse that he replaced. It was blown. I replaced with a 15 amp fuse, check the voltage unplugged from the blower motor and, voila, power. As soon as I plugged it in, checked it with the voltage meter again, nothing. This time, I can't find a blown fuse. Where is the blower control box? Could this be part of the issue now?

What is the voltage reading at the highest fan setting? Then check the readings at the other four settings too, and tell us.

I am wondering why fuses have blown? What was the number of the blown fuse? Are there any others that have blown or have been changed out? Give us those numbers too.

It was the 10 amp fuse to the programmer that blew. Now nothing and no blown fuses. I'll get readings at various fan speeds later today hopefully.

Oh, and I pulled the blower motor and it didn't spin very freely. I used some good ol' WD-40 on the bearing and it spins much more freely now. Now if I can just find the lost connection...

Need to know the fuse number - The programmer does not have a 10 amp fuse.

Okay, um, duh. I can't get any readings right now because I have no power to the wire. Are there any other fuses between the 10 amp fuse to the programmer and the blower motor wire? I have power to the fuse, I tested that.
