Hoses can you tell me what the hoses are that are coming throught the firewall on the passenger side of my 2001 Buick Century?? my car keeps getting hot and the pcv valve and that little hose have been changed.

its probably the actuator. its usually located under the dash in the center. you might be able to get to it by removing the glove box and looking to the drivers side. its a black box that has a wire connector on it. switch your heater control from hot to cold and you should here it click. replace it and i bet your problem is solved

Whenever I see a system which is leaking from more than one or two places, I do a head gasket check because that tells me that the system is experiencing above normal pressures. the wet floor is a heater core. whether it's a water pump or some other thing near it only you can tell. Actually it rarely happens, but the wet floor could be the hose where it meets the heater core at the firewall; again, only you will be able to tell the difference. if the hose connection looks dry, assume that it is the core itself.

Sounds like the condensate drain is clogged. for this you need to jack up the car and support it with 2 means. from the bottom look up just inside of the passenger side frame rail on the firewall is a rubber hose sticking out about 1 1/2 inches stick a wire in there and clean it out. You will get water coming out when your done.

driver side a/c comes out hot passenger side is ok played with the driver side switch got it to come out hot on red. Why can't i get hot and cold to come out the driver side? The car only allows me to use one or the other.

try checing the vacuum hoses-may be difficult to do this--get manual at store--the connectors and lines are probly failin

My 02 Century has dual temp controls . One for driver for passenger. Make sure you don't have the dual climate enabled and just set for heat on your side and AC on the passengers

vent your vent port one your port may be block or you temperature sensor giving trouble

u will need to replace the passenger side air temperature control blend door actuator motor.

drain hose for the a/c system is clogged check under the car should be about 2-3 in hose check it for a clog
