We recently noticed that the passenger's side vents are blowing warm air with the A/C running while the driver's vents blow cold air.
Reading old threads here there are a few mentions of it being the blend door:

Which was my first assumption since the driver's side blows cold. But, I also came across this thread where it turns out a valve was leaking:
http://www.explorerforum.com/forums...ide-blowing-hot-while-on-cold-setting.449782/
I took a quick look under the hood and I can see 2 ports. One to the front right near the air filter and another to the front left next to the power steering reservoir. I am not sure which is the high pressure and which is the low-pressure port, however, what I did notice was that the port next to the power steering reservoir was dirty and when I removed the cap there was what appeared to be some liquid on the port itself.
If the port is leaking, is there a way to replace just the port? or does the entire hose need to be replaced? I can't figure out part numbers for the hose or port, to be honest. That is of course assuming the port is leaking and the cause of the passengers side blowing hot air.
Is the quickest way to test it being a leak to buy a can of r134 from an auto parts store and recharge the system that way. If both vents blow cold then it is more likely a leak. Can someone confirm the high and low ports so I hook up to the correct one!
Thanks.
