Heating And A/c Issues

[jonmowa]

hey guys just recently i installed a new head unit, amp and such and every thing was working fine, i then decided i wanted to run all all the wires under the carpet, took every thing apart put it all back together and now for some reason my vents will only blow hot air, even when the climate control is turned off and fresh air is forced in from driving it will be hot. Has any one had this problem or how to fix it ?

check the little hose (like a piece of vacuum line) that runs to the vent on the dash (small little hole or a few small holes to the left of the steering wheel, not a proper air vent). pretty sure the climate control uses this to suck a bit of air back in to gauge the temperature.
