Anyone had this problem, or advice on it:

My 93 4.0L ranger now has 170,000 miles on it.

About 8 years ago, the original R12 ac system would no longer hold a freon charge more than about a 1 year so I retrofitted to r134a freon with r134a oil with stop leak.

System has worked fine all these years but now a terrible freon/oil sickly sweet smell is leaking out of the ac dash vents causing headaches in people with the vents blowing in their faces whenever the ac is turned on and continuing shortly after being turned off.

Guess it's the evaporator or some o ring seals leaking.

Not sure how hard it is to determine the point of leak and repair or even access the evaporator.

Any advice or suggestions besides, not to use the ac till repaired, would be great.

You can get a uv dye kit at auto zone for $30-$40 jut put it in the ac system like your filling it with freon and then use the glasses to see if you have any leaks
