Hey Guys,

Updates today on my AC problem - Turns out it is the Aux Fan.

I took the truck to a shop this morning on a recommendation and they did a great job. For those in the Vegas area, they are called Top Car Service, 980 N. Nellis.

First thing they did was evac and reload the R134a to stock. The AC did not kick in. Then they hooked up the computer to the truck and was able to turn the compressor on and off no problem. The aux fan would not engage no matter what was done so now I know. Total charge for about 45 minutes of working / joking around = 0 dollars. They even knew I was going to replace the fan myself and offered to doublecheck the system once the new fan was installed. How is that for "not-even-a-customer-yet" service?

So as far as replacing this aux fan, there are many options on ebay for various quality and price fans. Looks like a lot of them are probably made in China so I don't place too much trust in those. Can anyone who has a successful swap of this fan let me know what brand you settled on? Definitely will not be paying through the nose for a BMW replacement.

Cheers
Bernie
