Worn motor mounts can cause the motor to rise during acceleration, causing a clunking noise and possibly damaging the AC hoses. Damage to the AC hoses can cause a loss refrigerant resulting in no cold air from the AC. The motor mount will need to be replaced prior to repairing the damaged hose or the problem will continue.Google+

I didn't realize I had a motor mount problem. Thought the trans was slipping. Drove it that way for a long time until the muffler dropped down from its holder in the rear.
Lo and behold, it was the front motor mount and when it failed, everything came apart.
I read that leaking power steering fluid can erode the motor mount below it and the air conditioning hose below that. I brought this to the attention of my mechanic (THREE comebacks on this job and I had him replace the AC hose. Instantly I had wonderful AC...I had given up on that the previous summer :-0
Car's still not right and he went out of business! But the AC is great.
