Need some help here -

<!-- google_ad_section_end --> <!-- / icon and title --> <!-- message -->I have a 1999 F250 Super Duty Lariat PowerStroke 2 wheel posi - My A/C only blows out the defroster vents - I checked under the hood & on the passenger side there is a little black box that has a vac line tee with hoses - all seem tight - there is a hose connection off of this box that is not being used. Now I have owned this truck for about 4 years & the A/C has always worked this way

Called the dealership & they quoted - 1,100 - 1,300 to tear into the dash & find the problem & any parts would be xtra - well no way can I do that

Taking a trip out west late spring & will need that A/C to work correctly or my wife will B&M the whole way so Please someone anyone HELP

Kind Regards

Is the unused connection capped off? If you unplug the connectors one at a time, then put your finger over the open hole at the box, do you get vaccuum at any time?

If you have a hose off the vacuum canister the pump will run all the time. Does your pump run when you turn the key on? It is on the passenger firewall, just in back of the oval shaped vacuum tank.
