Update

[Sheenanny]

I found out that it was the fan switch that was blowing my fuses. Got a new switch and now it only works on high. Also, when I had the heater & A/C control panel loose from the dash to put in the new switch, I noticed one of the vacum lines is missing and another is cut right outside the firewall. I don't know where the heck these are supposed to plug in. Does anybody know where I might find a vacum line routing diagram or anything that might help?
Thanks so much!
