Did this video help you?

Ronny Patterson: I have a 2003 Cad DeVille the actuator door mod. has gone bad.  It was clicking and then the air would only come out the defrost holes.  A friend pushed the door so the air comes out the front vents because the mech said to replace it they will have to pull the whole dash out to replace it.        Is this true or can I do it.

john taheri: Hi i have 1997 cadillac deville  with digital dash and the gas gage need to be calibrate please if you have vedio for this or make i will be appriated thanks john

cameron collins: and yes all components under hood are working properly and charged to right levels.

cameron collins: will this cause my temp to not reach desired coolness, im getting about 58 degrees coming out of vent with my thermometer.  I was told it should be around 40 inside the vent.  I guess im asking if the module could be stuck between hot and cold with the dampening door?

koncreteprobeats: I am having about the same problem. I have a 2000 cadillac deville I have to keep putting freon in my car when I do it might stay in there for about 2 days or so but after putting it in it runs cold on the passenger side and warm on the driver side. I have put one large can of freon stop leak and today a small can of stop leak freon in the compressor cuts on once I start putting in the freon. but ac runs warm on driver side they to me I have 5 different temp door actuators but we is the one for the driver side. can you please help 

se7encapadon: Ok thanx

se7encapadon: I have a 95 deville, what if it blows good heat when it's on 90 max but soon as I turn down to 85 it comes out of all vents and gets cold? Thanx in advance :) 

77TRYTON: is this pretty common?

Steven Brown: I would like to personally thank you for this video. I have a 96 Cadillac Seville SLS. The passenger side was blowing warm air and the drivers side and rear compartment was blowing cold when I was trying to turn on the heat. I pulled the code from the car's computer and found out the blend door was not adjusting at all. The only difference is that the panel on the bottom has 3 screws instead of the plastic clips. Thank you again. Without this video, I probably would have taken my car to a shop and be charged and arm and a leg!

Richard Cha: rcmjr94, I have a 1999 Cadillac Deville, and my has the exact same problem
as yours.  Air only blows out to the defroster vent and on the floor.  How did you get yours fix?  Please post.  Thanks.

1A Auto Parts: You may want to check the engine compartment for a broken or loose vacuum line, also check under the dash to see if anything's loose. Hope this helps you out. 1aauto.com 888-844-3393

Iya Honey: Hi I hope U can help with my prob. I have a 94 Cad Deville. Air would blow through the defrost no matter what you set it to. I thought I fixed that issue by replacing a motor in the ac programmer.@ Two weeks back, air blew through the vents but it would not get hot. As of today it blows back through the defrost & still does not blow hot.I would really love some heat, I almost don't care where it blows. Please and thank you. Sorry 1 more Q the actuator U replaced I don't have. Is that possible?

1A Auto Parts: It might be,it could also be a bad relay, fan motor or resistor. 1aauto.com 888-844-3393

Keke Brown: I have a 1996 cadilliac deville and the fan comes on when turned on but goes off then back on every few seconds could this be my control switch?

1A Auto Parts: You may want to test the switch and the blower motor with a test light or an ohm meter to see if there's power going to them. Hope this helps you out. 1aauto.com 888-844-3393

Sam Sanchez: Hello I have a 94 Cadillac Sedan Devile, and I can not control the ac and heat ! when I start the car everything lights up find for a second then all I see next is --- and that's it. any ideas on what is causing it ? thanks.

1A Auto Parts: You may want to check the blend door actuator to see if it's working correctly. 1aauto.com 888-844-3393

Heartless & Hopeless Records: i have a 02 deville the ac only blows cold air on one side what could it be?

1A Auto Parts: The actuator is located in the same spot at this but the part might be slight different that the one shown.

melody oliva: i have a 2000 cadillac seville sls is the actuator in the same location? driver side is blowing hot air and passenger cold air.
