Aftermarket AC smells like oil

[Tbrett4]

Just bought my first bug. It's a 71 super beetle. The AC wasn't working when I bought it. It had a ground wire that was unattached and dangling. I got a good ground connection and now it works... It just smells like I've got mechanic scented air freshener. Anyone else ever run into this? Know how to fix it? Pic is of the brand and serial number.

Spray some Ozium through it while it’s blowing.
Might help.

I'll give it a go! It doesn't seem to be burning oil, so I don't think that's the culprit.

The air intake should be at the evaporator case under the dash, and exits also through the evaporator vents. So, unless there's a refrigerant/refrigerant oil leak inside the evaporator, the smell must be coming from something in the evaporator case.

It might just be from age… run the A/C for a while and see if the smell goes away. By the way, that’s not aftermarket, that’s original A/C that was installed by the dealer when the car was new.

Update: got under the bug today. Refrigerant hoses are cut, got under the car and discovered I have a very slow oil leak. It hasn't dripped into my driveway, but I can tell there's fresh oil from somewhere. I'm guessing it's burning just enough to make the smell. Will have to check in more later.

@cusser, I split time between Chicago, IL and Chandler, AZ-you would be surprised at how rough the Chicago Summers can be. When it gets to the mid to high 80s, and humidity that the Phoenix area does not see, I find that it is more uncomfortable in IL than AZ even when it is 15. I run a/c in most of my air cooled VWs in both states (my 67 which I keep in AZ lacks it, although I have considered adding it-it has a 2332 cc with 48IDAs so it would be a challenge to fit though.

That's correct. The blower kicks on, and essentially is a fan but does not blow cold air.
