I have done a search and so far there is no data as to where the drier is? I have a 91' Civic Si. I opened the R12 system and now im going to switch to R134A and i know i need a drier and an a/c flush. But i cant find the where the drier is under the hood?! Is it under the dash behind the glove box? Can anyone provide some pics?

 

It's a cylinder set in a hole on the driver's side next to the windshield wash bottle and the radiator overflow bottle. It has 2 hard lines going to it from the condensor.

 

I see it now. Thank you for the help!
