MDX 2003-195K miles. Compressor makes clacking noise-louder when car started. Local mechanic in Virginia wants $1300 to replace compressor. Since I will keep the car for another year, I do not want to spend that much $$ on a new compressor. Is there a way I can "disengage" the compressor so it does not make noise? Also, someone told me that it may just be the clutch. Is that possible if it makes noise and does not seem to seize up? Help! Thanks.
