Loren Unless they have changed the controls from about 1990 or 1991 your controls should slide up and down and the fan speed control runs left and right at the top of the control panel if this is the case then you should find 2 screws at the bottom of the control pamel they screw in vertically from the bottom. Remove the 2 screws and you can pull out the bottom and remove the pamel. Be carefull because behind it you will find 2 or 3 electrical connecters, 2 linkages and a searies of vacuum hoses. See if there is any thing binding or if there is any broken plastic or if any of the vacuum hoses are not connected. That is likely where the problem is. If every thing checks out OK there then you will want to check out the flappers them selves. You might have to get under the dash and remove the plastic covers take note of where every thing goes because they tend to put a lot of screws in those covers. I would start with the middle cover and see what you can find. I cant help you much beyond that since I dont have that model and am not sure exactly how it is set up . Good luck Robert

The flapper is not opening up when I turn the controller to defrost. The air flow is changing direction but will not come out. I can tell the flapper is sticking, and wondering where to look to locate it. Can I get to it from the duct coming from the fan under dash area? The less I have to remove, the better I will feel.
