My 97 marquis still clunking more than it should, Should i ad another can of freon? The intermittant clunk was worse .......before this last can of freon i put in it ,last week..[clunk is the compressor cycleing .[ automatic heat and a/c on this LS model[. what do you think bob s thanks for reading

 

the clutch is wearing out on my 86 grand marquis, and the clunk/compressor was a freaon not enuff issue, the problem i still have is some sort of diaphram/inner line filter that is not letting enuff freon get into the accumulator, according to my mech friend : )
