Default heater problem IS300

Hello to everyone.

I have a 2002 IS300 with a heater problem...temp gauge stays in the middle, does not overheat, does not make any type of noise, it has 144k miles but here's the problem...

driver side vent on the left and the center vent(left side) blows hot air, the passenger vent on the right and the center vent(right side this time) blows cold air, happens intermittently...at worst times you can smell something burning especially when your at a stop.

settings on the heater is max heat, fan is either on max or auto....air is fresh or recirc. it does it on either settings...

one forum from uk said it might be the servo, just wanna get some more info, thanks in advance!
