A/C & Heater not working properly!

Well this problem has been going on since winter. I have a V6 2000 Taurus, 120,000 miles, automatic and in the wintertime the heat blows for about 10 seconds then blows cold air from the outside. Now, during the summer, the A/C doesn't blow COLD air, you can tell it's some A/C with a lot of ambient air. You can hear the A/C clutch engage and put a load on the engine, but it's just not working. When I turn the hot/cold knob, you can't hear anything move behind the dash, like the door is not working back there. Can someone help me out here?

Thanks,

Kevin

Thanks for the guidance so far. Pulled and checked fuse 32, it's good. Did the blower heat/cold check just as you said, did not hear anything except the blower. I remember I used to be able to hear the door flap back there, but not now. Switched the knobs, still nothing. Standing by for further instructions!

OK, I went out and got the actuator, cost me 77 bones. Replaced it, it was actually pretty easy, took about 45 minutes. I left the bracket off the bottom that protects the door linkage so that I could verify movement, and it does move the entire range. I took the car out, and now I get HOT air when I have the temp to hot, but little to no AC when the AC is on and the temp is set to cold. Wondering if the freon is gone or some other component requires inspection. Anxiously awaiting your response,

Where can I find this low side port? I see the one sticking up in the front on the passenger side with the black cap but my coupling will not attach to it. I have read I need to find the port with the blue cap, but I cannot seem to find it!

As for your test, yes, the fan comes on and I can hear the A/C clutch engage and disengage about every 5 seconds. But until I find the port I can't check or add.

Thanks

OK, I'm filling it now according to the instructions, I can feel the can getting cold, but the compressor still strokes on/off every 4 seconds. Do I need more refrigerant?

I know you don't want me to pay attention to the gauge until the compressor stops cycling, but the needle goes from the very bottom of the good range (when off stroke) to the top of the good range, (when on stroke), and has kept doing that since I connected the can. Am I doing something wrong?

SIR! YESSIR!

How long should it take to discharge a 14oz can? I've had it hooked up for 10 min or so.

I can still feel liquid at the bottom. I shake it a little bit every minute or so. But I'm going to go get another can. As an aside, I can tell that the air inside is much cooler, just not as cool as I'm used to under MAX A/C.

Going to go get some more refrigerant, will let you know when I come back. You've been a HUGE help!

I was using norm. 10 seconds after I started the second can the compressor clutch engaged and stayed engaged. I closed the valve and checked the gauge. Now, instead of fluctuating it stays right in the middle of "good", and the AC works great! Do you recommend any kind of additive sealer?

I take that back. After I emptied the first can, I disconnected everything and drove the car for a few minutes. Put the AC on MAX, and I didn't check the knob apparently before I put the second can in. So when I added the second can, with the engine running, etc, the AC was on MAX. What do I have to do now?
