So we've my wife's NB for almost a year now and it has reared its ugly head on why it is the battle bug. The heating and air conditioning system has progressively gotten worse since then. When we got home with the car, we noticed we couldn't change the air flow gates to move the air from feet, body, both, and defrost, and it was blowing some dark green/gray foam out every now and again; but that was okay because the heating and air still worked. So the first question is how do we fix that. Once summer got here we noticed that the A/C would only work every other time we started the car up, and sometimes we would lose the A/C or gain the A/C after driving around for a while. Question two is how to fix that. The final question is now that winter is here, the heater never really heats up, and like the A/C sometimes after driving around, it will randomly turn on, but it will never be hot like heaters are supposed to get. SO therein lies the last question.

I checked the coolant and the reservoir and the radiator are at normal levels, but the coolant is a blue green color. Isn't G12 an orangish color? Hopefully that is the easy fix to that problem if they dont have G12 in it. lol

I would start with a coolant flush and a new thermostat to hopefully take care of the heater problem. WIth that green coolant the system may have what could be described as slime throughout. The thermostat may be stuck open or not closing fully which will make it only warm some of the time. The coolant should be what I consider a pink color, some people call it lilac. has to be G12.

I would worry about the rest next spring.

Do a search for "blend door" issues. There is a do it yourself instruction deal on here somewhere. Wow that was technical talk wasn't it? LoL.

Here is the Blend Door DIY it might be helpful ...

G12 is Pinkish-Red in Color and CANNOT be mixed with any other auto parts store anti-freeze. It will cause a "Peanut Butter" type material to coat the inside of coolant system reducing the flow of coolant. I agree with bme a coolant flush might be needed.

"Peanut Butter"

Perfect description.
