is there a relay under the dash for the blower motor door in a 99 ford explorer
There are seven relays under the dash~
there's a relay box under there, have to search some more~
there's a relay on here~
There are things known as vacuum motors which are really just vacuum operated valves which direct the air to whichever vents you select. If you hear the blower motor and you can direct air to certain positions, it is likely one of these vacuum motors has failed or one of the vacuum lines going to them has a leak.
hans is correct this is a vacuum issue not a relay issue.
do you hear sucking sound like from a vacuum leak under the dash when engaged?
really frustrates me when Ford, GM and Chrysler chose to use old fashioned Butyl Rubber which degrades in less than ten years, becomes rigid, loses all supple qualities, then splits...silicone will never do this, MZB, MINI, BMW all know this and use only silicone vacuum hoses, like dopes we put out an entirely disposable product which screws things up in the future, like automaker "save money now, make it harder to get along with" or do it right and just use silicone replacements....same with heater hoses, do you think the cops would use anything than the very best on their police interceptors...no, only the best~
