My 04 GMC Sierra SLE blows cold only on the passenger side

Customer Question

My 04 GMC Sierra SLE blows cold only on the passenger side and continuous heat on the drivers side.
JA: Have you checked the coolant level? Has there been any leaking from the hoses?
Customer: No Leaks
JA: Are you fixing your Sierra yourself? What have you tried so far?
Customer: I Only added 2 cans of refrigerant and noticed the difference in cooling per side. No leaks found and all vehicle fluid levels are good.
JA: Anything else you want the mechanic to know before I connect you?
Customer: None other than what is already mentioned.
