Ok so I finished replacing the heater core, blend door and blend door actuator this last Sat. in my 2001 F150 extra cab. However now when I turn on the heat or air no air comes out. When I turn the climate control **** I can hear the blend door moving but I get no air when I turn up the hot and cold **** or the speed control ****. Any ideas what would cause this to happen? I had air flow before just no heat. I checked all the fuses in the drivers side fuse box and all were working. I'm thinking I must of missed connecting a wire that controls the air controls. I thought it may have been bad control board so I replaced that and still nothing. Any ideas what I need to check?

Thanks,

Are you saying the blower doesn't work?

Do you have manual or electronic climate control?

 

Yes and manual.

 

Did you reconnect the blower motor and all the other plugs and connectors?

Did you check the fuse and relay that are specific to the blower (see owners manual for listing)?

 

I did go back and check all the wiring and found that the wire to the blower was not pushed all the way in. So that fixed the blower I now have air but still no heat! Not sure what to try now?

 

Verify both heater hoses under the hood are hot. If so, the blend door isn't isn't moving. Check the connectors for the BDA & temp control and that the **** for the temp control isn't stripped.

If both hoses are not hot, then the problem is under the hood (air bubble, water pump, coolant level).

 

Both hoses are hot. I took the blend door actuator out and plugged it in and it does not turn. So I got a new one today.

 

So I hooked up the actuator but did not install it. When I hooked it up the temp control was turn to heat so it rotated and stopped. Then when I turned the temp to cold it did not rotate it just set there and shook. Here it a pic of the actuator and box with part number. Is it a bad actuator or can there be a problem in the wiring causing it problems.
