Since this thread will catch the interest of the 116 crew, I am responding here. Please see the link attached and chime in if you think you can provide any help at all. The link will have another link attached which was my first post. I love my 1979 300SD but if I can not resolve this a/c problem I am thinking about moving on. I live in Manhattan and commute back and forth to Brooklyn every day. The summer here can get brutal. Now add in the fact that I sit in bumper to bumper traffic on the FDR everyday with cars blowing carbon monoxide. Now picture yourself on a 90 degree day with the windows open with 90% humidity and no a/c. I have about three to four weeks to resolve this a/c issue or for sale she goes. I have tried to figure this fuse blowing issue out and been through 2 blower motors (only paid for one). I have had anybody and everybody I know look at this issue . I just can not figure it out. Does anybody think that maybe I have a push button control that needs to be resoldered? Maybe there is some relay or voltage regulator that has gone bad? Right now as of May 13th I can get the system to work on the low setting only. Fuse will last about 4 or 5 cycles before she blows. Horn came back and is now working normally and at full volume. This I can not explain. Any and all thoughts are welcome and appreciated. Us 116 boys need as much representation on this board as possible. Show those 123 and 126 boys who dominate this board that we are here as well!!!

Please I need 116 Help!!!
