'88 Ford Ranger XLT
I'm having the same problem; if you get an answer, please forward to me also, OK? Thanks, BMP My A/C works great, blowere motor runs great but unless I close everything, nothing but cold air comes in. It just started recently. I replaced the heater core last year and the temp control gets to the middle and engine is very warm but no warm air comes into the cab? What's going on?
