I went out and tried to disconnect, but could not get it to come apart at the connection there. Is there a clip on that connector that has to be pushed in? I noticed something on one side of it, but it does not appear to be anything that has to be pushed, etc. I am guessing I should just use a little more force? If its not the actual fan motor, what else could it be?

BTW- if it is indeed the fan motor on the fritz, about how much $ are we looking at? Probably $$$ I suppose?

Also- will a fan from a 300D or 240D (78-85 era) also work? I am wondering what all years are compatible, incase I have to go the salvage yard route, which I probably will do anyway.
