I'll see about checking into it. I am curious if it is worth it considering that the ac has worked well enough to keep me cool for two summers here in summer arizona.

Thanks for the info and help.

It turns out that the oil seperator, black box under the intake manifold, was not working properly. I attempted to clean it out with carb cleaner and air but the car failed again within a day or so. I read somewhere that most people didn' have luck cleaning it. I bought a new one from the dealer for...

Does anyone know what these two flashing orange lights mean?

They are on the AC control next to the on/off and AC bottons. The AC system works fine and has done so for over year but occasionally the lights flash. AC functions fine in Phoenix AZ no degradation noticed in operation.

I had the exact same problem with the same year and model 2001 s60 non-turbo. The rpms surged up and down at idle. I was told it was maybe an oxygen sensor but that didn't pan out. It turned out to be a clog in the PCV system. The bottom line to the vacuum cannister was completely full of carbon dep...

Had a weird noise at idle, goes away while driving. Discovered that noise goes away when you loosen oil cap. ...

The car has 100K miles on it. It is an S60 non-turbo. The check engine light was for lean fule mixture on bank 1 (OBD code po171). I recently had the timing belt and water pump replaced (unrelated preventative maintenance). Checked the oxygen sensor with a multimeter and both are working fine. I was...

Occasional ABS light. Brakes work fine, fluid levels are good. What is the most likely cause? Is there anyway to narrower this down? Maybe get rid of the light?

Recently got a check engine light, it has been intermittant past few days. Lean Bank one code. The car is surging at idle between 550 and 1000 RPM. There is also a loud squelling noise, almost a whine. Not a belt and no vacuum leaks. Any ideas on the noise? Going to try an o2 sensor for the check en...
