My 1997 Jeep Wrangler's AC Compressor/Clutch makes a clicking noise when it engages and disengages. Is this
a.) normal (not to worry about, just ignore)
b.) going bad (gonna have to repair or replace soon)
If it is going bad is it just the clutch or the whole compressor assembly?
How much does it cost to repair from a fair mechanic?
Here is a video I posted on youtube of it doing it
