2005 taurus probllem
 

started with the locks opening and clossing on their own, later the horn would go off while the car was parked, now the car starts but wotn stay idle and dies. My ac compressor just went bad? and that still needs to be fixed, could that be anything to do with this , or is this an electrical maybe computer problem?

As for your door lock problem , check the harness from the doors to the car making sure that no wires are crushed . May be related to the horn also.
Your starting problem , does the car need a tune up ? Plugs , air filter , fuel filter maybe a fuel injector cleaner treatment ...
As for your A/C , you were vague in your problem, went bad HOW ?
And no , all your problems are lot all related.

I check the fuze box inside the engine compartment yesterday after reading here about someone with an ac compressor trouble, turns out the fuze for the ac compressor clutch, and pcm was out i replaced that, car starts again and idles ok, but when i rev the car it stalls around 4000rpm, wont cut out just the engine chokes. I know my ac compressor is out car blows only hot air and there is a noise like bearings or something coming out of the compressor pulley. got a cheap obc 2 code reader was i was unable to get the codes with the piece of junk. Car had a tune up done early this year, plugs fuel filter oil, the works.

That is normal operation for your vehicle. The PCM cuts the fuel off at that rpm to prevent damage to internal engine componets. It should keep on going if it is in gear.

ok, now, the car still makes a little grinding noise, coming from the ac compressor , and blows hot air.

Update, i had a friend look at the car, he said the compressor clutch was nor turning when I had the ac runing, this automatically blew the fuse on my engine compartment, #18 (clutch relay switch and pcm keep alive switch). I bougth a set of 5 fuses and everytime i had the ac engage the engine stalled after a few minutes and the fuse blow. Does this means i need to buy a whole new compressor or just the clutch assy. Also how hard is it to replace that?
thanks

You probably need to replace the compressor. If you are not familiar with a/c work, I would let a professional do it.

ac compressor replace, now car runs very nice, but i still have that power lock problem, yesterday they were opening and closong so bad i finally had it and pull the fuse, now i have no power locks , but at least that open and close crap is over, i would however like to correct the problem, if anyone had the same problem, maybe is the anti theft alarm, i dont know, the horn went off some time and wouldm not stop also.
