Congratulations...you've got it the classic symptoms:
- Low temperature output on passenger side
- Wide (20+ degree) temperature spread between the driver/passenger side
In a place like Virginia you might be fine 360 days of the year. Are you still covered by the 5 year/60,000 mile warranty?
So for the heck of it, I ran the same test in one of my other cars. I have a 1-owner 1999 Mitsubishi Eclipse (2.0 non-turbo) that we bought brand new. It has 170,000 miles and has its original heater core. When I run this test in that car (close to 0F outside), I get almost 150F from all the vents...and the temperature actually gets hotter on the passenger side. This is what you would expect since that's where the heater core is located!
Here's a pic for Eggman... Hate to see the car this dirty but this is the best I can come up with right now...
