Sounds like a bad ac compressor

Sounds like you got motor oil in your coolant. What does the motor oil look like on the dipstick? If it's the same milky, muddy color and thick, you need to have some major work done. Either a head gasket or cracked head or block. If the motor oil looks OK, you need to drain, flush/clean, and refill your cooling system with fresh coolant. I would strongly recommend having an experienced mechanic check it out for you.

Have you replaced the filter and fluid every two years or 24K miles? Try fresh filter and fluid as a cheap possible fix.

Just here and there , you hear a "click" while a.c is on... Ok, turn the a.c off , see if the "click" disappear's ??.if so... I,m guessing it's the a.c compressor clutch kicking in and out of the system as it is required to do. turn the a.c off , if not , you need someone in person to search out the "click" , past that ... turn the music back up and cruz !! , lol... good luck !!!!

Blue smoke is often the result of bad rings on the pistons. Engine rebuild time. It is possible that the turbo is leaking oil into your engine.

take it to a power steering specialist shop and have them check the drive belt first and the the power steering for failure

Motor mounts

Inside the key fob are contacts that get dirty, both the electric side and the push button side, carefully clean them both.
