Re: Ac cold at idle, gets warm
Fords had that problem of either low charge or bad cycling switches. What happens (low charge) is the refrigerant system will quick cycle when going down the highway. At idle the temps will be fine. The first thing to do when you have most AC problems is to verify the correct charge.. and thus elimi...

Re: Weak Compressors, or bad orifice tube?
You can not get an accurate temp using an infared thermometer due to emissary problems. Depending upon the reflectance of the metal the reading will vary. That is the reason why it is suggested to "shoot" an area that is black. If you shoot an area that is shinny, both in and out of the ac...
