Only cools at highway speeds.Radiator outside cleaned-At idol does not cool, when in motion begins to cool but again not up to par. How do I check doors that control heating and cooling?Would appreciate any input.\015
If you have a modern car, say a 2000 Ford Taurus or newer, a small $5 specialty screen in the cooling system pipes referred to as an "orifice tube" may be clogged up. When the system is opened up for a compressor replacement this must be changed because pieces from the bad compressor cause a mud-like substance to clog the filter and prevent circulation of the freon. You should discharge the system, replace the orifice tube and recharge the system. This is just one possible cause. Other causes could include freon "leaking" from o-rings that are old, failure to replace the evaporator (should be replaced when compressor was replaced) and a possible vacuum leak keeping the vent doors you referred to from moving properly (would blow heat in the engine compartment if that was problem).
Feel of the large ac line going into the firewall,and see if it is cool,or cold,also,the condenser could be restricting flow threw it,on the inside,we really need gauge readings for low side,and high side to diagnose the problem.
