I have a 99' GTP with 118k miles that just turned 12 last month.
As the weather here has turned cold I have noticed while the fan seems to be running fine, the actual air is not coming out with nearly the force it should from the vents. Actually, it seems like there is some air coming out from the front defogger vents, dash vents and floor vents all at the same time regardless of what setting I have them on. Anybody have any suggestions on how to go about fixing such an issue?
