I have a 96 windstar and when i turn the heat on the a/c compressor starts up. how can i disconnect the compressor or fix the problem?

Fuel pressure regulator?

Is the air inlet to the blower blocked, check it.

for a 96 ford windstar you have some fuses under the hood you might wanna also have the starter checked if it is just sitting there cranking

Remove the fuse for it, or unplug it, or turn the swich off for it.

Had you hear the a/c compressor kick on?

Unfortunately for you ( i had the same problem) The A/C compressor HAS to be in working order on these cars or else all heck breaks out with the climate control.

If it's a nice car, get a new compressor installed. If it's borderline- get rid of the car.

I paid 2200 to Cadillac to fix the A/C and climate control only to have the transmission fail in my '93.

I dumped the car soon thereafter....

probably low on freon R134A. Buy a can with a gauge on it. Addd to the low pressure port in engine compartment on passenger side, low pressure hose. If the compressor starts working, then you are low. Do not overfill or you will damage compressor. The gauge should have a "good" zone on it, stay in the god zone. If it starts cycling very fast, it is still low.
It should cycle 4 to 7 times/minute at 70 degrees F.

report back on progress.
Please rate as fixed if this helps.

Ford uses a relay system for the compressor clutch, have someone turn the a/c on while u listen for the relay to click. If you can hear it click check the compressor clutch wire (2 wire plug) to make sure it actually has power. the 6 and 10 series compressors that Ford uses are known to just fail all at once.

try the refrigerant level...if it had a lek and freon escapes...pressure switch will de activate compressor...

i hope i was ab;e to help...

tnx

pls rate me...

The compressor is the same but it may have a different pulley and the plug may be indexed on the wrong side. If you have a set of snap ring pliers you can put your coil and pulley on that compressor or it may already be the same ones just make sure you put the plug where it is on your original compressor.
