Was it blowing hot air out of both the driver and pass. side vents?
yep.Was it blowing hot air out of both the driver and pass. side vents?
yeah, I put both the driver and passenger side on the coldest setting I could.Do you have dual climate control (driver/passenger)?
did you add a can of AC Recharge or an actual bottle of r134a also, did the hissing go away after?Mine is/was doing the exact same thing. Over time, I noticed that the temps weren't blowing that cold, and lately it started blowing warm. Same kind of hiss noise too when on, but that only started lately when it started blowing warm. My low side pressure seemed low, so I added a can. Blowing cold again for now, but it must mean I got a leak somewhere. I'll see how long it lasts and determine my next steps after that. Probably have a shop find where the leak is, and then I'll fix it myself.
It was an actual 12oz bottle of r134a. I happened to have one around so just gave it a try. Yes, as far as I can tell the hissing has stopped for now.did you add a can of AC Recharge or an actual bottle of r134a also, did the hissing go away after?
