AC has a BRAIN of its own!

Hi Guys, here is OZ, the summer can be really hot. My early E60 with M54 engine is 11 years old now and the AC works perfectly fine. But, on some summer days I have noticed that the AC will lose all of it cold temprature as if it is nearly turned off or low. In order to get the cold temp back, I need to increase the the blue bars on the climate control or increase the fan speed. Is this normal?

FYI - The water pump was replaced 60K's earlier as preventive measure and is still working fine. There is no coolant leak or AC leak as it works fine usually.

I have found that once in a while the bar colors will change from blue to red or the reverse without action on my part. I just reset them and all is fine.

That will happen if you press the Auto button with AC on. But problem I am trying to figure out is different.

This sounds like a feeon issue. R134 has much smaller particles and has to run under higher pressure to give the same results. It also leaks more easily than the old R12. you probably need a pound or so. Any standard service place should be able to do this. You can buy cans to charge yourself, but if you are not clear on low side vs high side you could have a bad experience.

Okay, after turning DIY'r for over an year now and thanks to all the good people on this forum, I thought I knew a little about my car. But from you just above, it sounds like a foreign language . Can you please explain or direct me how to figure out this feeon, R134, R12 etc etc . Here in OZ, all the mechanics are bad mojo, and the $tealers are real hungry, so at the end DIY is the ultimate fix of these cars. So, any further details on what you are saying would be great.

R-12 was used for years, but was not good for the environment. Car companies switched to R-134 quite a while ago, so your vehicle would be using the R-134 freon.

So, are you saying I am leaking AC gas (R-134)? I would doubt the leak, because if that is the case, why am I freezing sometimes, but not enough cold other times?

No, I can not determine whether or not the gas is leaking, but if it is, it would be R-134.

Does any one knows how to check the level of freons (R-134) in the car? I mean, does the AC system has enough gas (freons) or not? Does the level of freons go down over a decade without any leak???
