    thank you for the information I wil give it a try and see what happens.

  • ccn7 Dec 18, 2008

    no good bought new actuator 43.00 bucks still does same thing.must be the switch.

  • ccn7 Dec 18, 2008

    also when i took the actuator motor off i can move the linkage back and forth from floor to defrost with no problem. i test lighted the wires there are only 3 a brown a white and black but only the brown is hot when the key is on. when itested the other to wires i got nothing i am gessing one or the other is ground and the other is theone that sends a signal from the switch to move the electric motor to the setting you want. i hope someone out there can help me.

    No , it still blows on the floor it does not re-direct. I am going to put in new controls to see if that will fix the situation.

  • ccn7 Dec 22, 2008

    as to your comment dec. 19 i made a mistake it does re-direct to defrost when i move it by hand. in fact i got it set that way right now for defrost.i got a set of controls on order and should be here in about a week.

There is an electric motor that moves the linkage to change where the air comes out..its under the dash to the right of the gas pedal........the problem is likely the linkages form that motor to your blend door that directs the air.its called the Heater Blend Door Actuator
hope this helps.......Good Luck!

Just because the bottom blend door has been replaced does not mean it's fixed. Can you see under there when you actuate the heat for the floor? That's the only way you will know if it is fixed.

When I cut on my air or my heat it will not blow out the vent but it will blow out the defroster what is the problem 1995 Catilac sedan Seville


One of you motors in the heater venting system has burnt a fuse, burnt out or has come disconnected. This prevents a flap in the heater from changing positions and sending air to the floor or the defrost.
Have you had a heater core or motor replaced recently as the heater ducting needs to be removed for some of this work and it is possible to have problems with the heater venting doors not moving after the work is done.

Driver's side defroster and heater vents blow cold air but the passenger side blows hot. Both sides should blow hot The temp is set any temp and it still does the same thing. It is winter so I don't know...


The doors that open and close in the heater control unit are ran by motors. It sounds like a motor has quit in yours. When turning on the defrosters the motor closes the door to the heat for the floor

Heater problem


Check the heater valve on the engine firewall. If it doesn't open when you move the temperature switch to hot open the valve manually. If the heater blows hot air the cable from the switch has failed.

1995 Chevy k1500 heater problems.


For a 95 Chevy Silverado....I replaced the Blend Door Actuator on the passenger side. Just behind the slide out cup holder. Yo ucan acces easily by removing the ash tray piece and the glove box....Or just the glove box and work like hell to get a socket in a tight place.

There are 2 actuators....one controlling the (Mode and Temp 89018681) and the other the (Air Inlet 89018367). I called the dealer and the parts were 85-125. I got it From TBA Auto (local store) for 39.00. A 20 min job at most.

Defroster won't blow air


It sounds like the heater control panel is'nt opening the defroster door
under the dash. You need to check cables or vacuum lines under the dash to see if any came off the diaphrams or levers.
