1988 Jeep Comanche Pick-Up. Cannot direct air to dashboard ducts. Ventilation is now all directed to "defrost" and "floor" ducts. I have checked all vaccuum hoses and found no problems. This is a basic AC/Heat system without automatic climate control. Any suggestion to troubleshoot system is appreciated.

I have 1986 comanche 4.0,4wd. Does anyone know,the largest size tire, I can go with on a stock suspension?
