This morning, I had the coolant system on my 2008 ranger flushed. The truck was also in the shop for a bad EGR valve hose. Anyhow, once I got the truck back, I turned the A/C on (it was only 80 out, but the truck had been in the sun for a while). The A/C would only blow hot air. I turned the system to vent, defrost, etc., and while the air was redirected, no matter where I had it set, it was hot. However, when I set the truck to max A/C, then it blows cold air.
I took the truck back to she shop, and they insisted that it was working properly, since the A/C worked at Max. They also said that the only problem that would cause my truck to only blow hot air would be the blend door, which would require them to pull the entire dashboard, which would run up a labor bill of at least three hours. Obviously, I don't want to give those clowns any more of my business.
On one of the heater hoses, there is what looks to be a vacuum actuated valve. There is evidence of coolant leakage beneath it. I do have the Haynes manual, but it is far too general to even mention the purpose of that vacuum valve. So, my first question is what does that vacuum valve do?
I dropped the glove box down, so I can see the blend door actuator (a flat white box on top of an air plenum) as well as the wiring harness for it. Does anybody have a wiring diagram or plug pinout that can tell me what leads to check to see if the actuator is getting a signal?
I've seen youtube videos explaining that in order to get at the actual door, I would have to cut a hole in the plenum with a Dremel. Is that procedure recommended, or would I be better off having a pro take care of this? The truck is only 6 years old, and I still owe over 11K on it, so I don't want to butcher it.
Finally, it there anything that the my ex-mechanic could have done during the coolant flush that would damage my truck's ventilation system?
