nbo90745 Posted July 15, 2014 Share Posted July 15, 2014 I have developed and issue with my 2010 Ford Explorer ..When I am approaching a somewhat steep grade the Air stops blowing out of the dash vents...Once I flatten out it comes back on......This is when the air is heat or cool or just plain air..It seems like a vacuum issue..is that feasible....I don't want to go to the local dealer until I have some data to share with them..Looking for some help! Thanks Quote Link to comment Share on other sites More sharing options...
ajcomputer Posted July 15, 2014 Share Posted July 15, 2014 You're on the right track, sounds like a vacuum issue. Quote Link to comment Share on other sites More sharing options...
nbo90745 Posted July 16, 2014 Author Share Posted July 16, 2014 Will the dealer put it on the computer diagnostic tool to determine....You know if I take it on test it will work fine! Quote Link to comment Share on other sites More sharing options...
ajcomputer Posted July 16, 2014 Share Posted July 16, 2014 Most likely not. It's my assumption there is a vacuum leak(I've seen the reservoir leak) under the dash. Quote Link to comment Share on other sites More sharing options...
