What's wrong and how can I fix it? Can I still drive it?

The outer plate clicking on and off if what you mean is compressor engaging and disengaging - could be normal. A/C compressor is really two things. 1. Just a pulley when disengaged using a bearing for that outer hub called a clutch and when engaged that bearing isn't involved and shaft of compressor with bushings/bearings is operating and can make assorted noises normal to warnings of problems. Rapid cycling like that at certain temps and loads could be normal or pressures built up out of parameters and it shuts it down. If more than I could tell by the video it may take a trained ear with temp/pressure observations up to evacuating system of refrigerant, charging to exact known weight of charge for more infomation. At the age plain leaks and low charge can cause that and is common. The fix if so may not be. You need to know pressures, temps it's dealing with and engine RPMs to begin to know what is normal or not so far, T Hammer Time Ultimate Carjunky / Moderator Nov 23, 2012, 5:32 PM Post #3 of 3 (1783 views) Re: AC compressor clicking, video inside Sign In It's cycling on and off. It could be low on refrigerant or is could just be cool enough outside to lower the pressures that low. Some cycling is normal depending on outside temp and blower speed. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
