manual climate control issues

[240life]

I tried the search site and got no answers that could help me . I currently am not able to select where my heat blows in my 89 240 coupe. This situation happened around june but it is 100 degrees out and didn't care. I am no electrician i have only basic skills, my fuses are all good. By the way this happened when I removed my radio and installed the remote turn on wire for my amplifier, I did pop the electronics fuse and did not notice untill i had turned the car on and my HUD didn't work. I replaced my fuse turned on the car and every thing was gravy. The next morning I realized I couldn't make a heat selection and it will only blow on my windshield, is there any reason why the lights come on but I can't select heat on my control unit?

I wish we could PM on here, but I just emailed you. Did you find the solution? My car is doing this now.
