Hi guys, I have two questions tonight. I ready to check out my AC for the summer on my 850 Turbo Wagon. I checked out the compressor and clutch does not seem to click in. I dont know if the system is charged or not as I just bought it in Dec. Can you give me a starting point of things to check. 2nd question. I am getting a periodical loud clicking noise from under the distributor Hood. It seems to come and go....sounds electrical. any ideas of what to look for?

I taking it to my Do it yourself garage tomorrow so I was hoping for some ideas to look for.

Thanks in advance.

For Air, there is a valve just behind the passenger side headlight under the hood on one of the AC lines. Just take the plastic cap off and press the nipple thingy in the middle (its liek the valve o tires) adn that will tell you if you have some pressure in your system or not. Now this clicking noise you mentioned can be from the AC compressor ad it might be kicking in intermittenly if your system is just little low on freon.

 

Clicking noise is probably the valve on the driver's side of your fan, bolted to the fan shroud. Its part of your evap system.

 

I rechecked where the sound was, and yes its coming from I suspect is the EGR Controller....it has two vacuum hoses to it...now the question is, is it suppose to multi click like that every 3 to four min.

That should be the evap valve. Is it mounted in a rubber grommet?

If so yes that is normal after the car warms up.

 

Thanks a ton, saves me time to take apart and clean or replace.
