Hi guys, have developed an issue where the passenger side vent blows out ice cold air whilst the drivers side blow out mildly cold air. I have researched the forum and it looked like for most, the fix consisted of recharging the A.C system. I have done that which worked perfectly, but now about a month later it has returned to only the passenger side being ice cold. Suspecting there is a leak, what would be the next thing for me to check? Hoping it could be something that is DIY. Thanks in advance!

 

1st I would check and record both the low and high pressures at idle. Next if you can get a hold of a electronic freon tester check all of the fittings for a leak. You could also do a UV dye injection of freon and with a UV light check for leaks. If the freon is OK then you would need to have the mixing blades checked in the AC system duct. Most likely the dealer needs to do this. Good luck and report back what you found.
