Clacking sound from floorboard
 

Whenever I turn on the key I hear a loud CLACKING SOUND which seems to be coming from the floorboard where the passenger's feet would be. It goes on for about 20 seconds, then stops. It starts clacking again when I turn the key off and runs for 20 seconds. I can't hear it as loudly listening outside the truck so it seems to be inside the truck. It might have something to do with the heater/ac system. Also, if it means anything, there is no vacuum pump on the engine.

Any ideas out there?? :s:

maybe ball bearing in the heater cord :run:

I can't think anything that should be running on that side of thr truck after key is shut off when fine what is lets know

There is a door in the heater box thats acting up. I cant remember if its the door or the actuator that goes bad.

i don't think it will run with the key off i could be wrong i never had any problems with heater

They will do it for a little bit after the key is off. 95 and newer doesn't seam to have as many problems with the heater controls as the earlier ones do.

Any idea how to get to the heater box and/or actuator?

littler hands :w2: just joking not sure

You can take the glovebox out an you may be able to get to it.if not you've got to remove the
dash an metal tube frame in front of your heater box.

I'll look over the job tomorrow when we get temps in the 60s. Thanks:tu::tu:

i also here you have to remove the driver seat because have drop steering and seat will be in the way
