Question about 1998 Ford Taurus
Okay, we tested compressor by jumping it and it works. Blend door actuator has been manually switched from heat to AC. But, AC still won't come on. Any other possible causes? All ideas will be appreciated.

The temperature blend door actuator is located on the right side of the transmission hump under the evap. case. The floor ducts cover it.

i had the exact problem with my 2002 pontiac grand prix. i found a broken vacuum line that comes off the back of the engine. this vacuum line runs down the passenger side top wheel well in the engine compartment. it goes behind the battery mounts then traverses into the big wire harness just below the battery. the vacuum hose was broken there under the battery so i couldn't see it without physically tracing where it went. i took a little piece of rubber hose about the diameter of an aquarium hose and reconnected the hose. i now have cool air. you have to remember that this little vacuum hose keeps the climate control does open as well as close them depending on your hot-cold settings. this all occurs from the climate control knob inside the car. hope this helps. a real easy fix too...........phil

I guess first thing to find out is why compressor is not coming on, as without that running you won't get any cool air. May just need a recharge, but I would have that checked out first. If system is low on freon, it won't engage, and if it is low, why, as in where is leak & how much to fix it, would be my first concern.

Temperature Control Blend Door Failure No Heat or no AC (dependes on
where door sticks)
all modern cars there is a tiny DC electric motor driven gear drive
that moves a plastic door that blends heated and cooled air from the
AC and the heater core, this is called (interestedly enough) the air
temperature control blend door actuator. The motor that moves this
door fails because the door starts sticking from warping, most common
complaint is no heat but it can be no AC as well. To replace these
parts (blend door and blend door actuator) you must remove the entire
dash from the car. Always have this problem confirmed by a dealer or
qualified repair shop as it is a very expensive repair.
Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.
