A/c & Heating Problem
I HAVE A 1998 RANGER WITH A 3.0. THE ONLY A/C SETTING THAT
WILL WORK IS MAX A/C, WHEN SWITCHED TO ANY OTHER SETTING
,INCLUDING OFF, ALL I GET IS FULL HOT HEAT WITH NO TEMPER-
ATURE ADJUSTMENT.THE THING ON THE HOSE THAT LETS COOLANT
INTO THE HEATER CORE IS CLOSING WHILE THE MAX A/C IS ON
BUT NOT WHILE THE REGULAR A/C IS ON. IS THS A VACUUM ISSUE
OR SOMETHING ELSE? I HAVE ALREADY TRIED CHANGING THE CONTROL PANEL BUT I STILL HAVE THE PROBLEM.
