| Post subject: | 2002 3.7 liberty & heater & ac |
I bought this vehicle with a rod knocking . I installed a crank kit & the engine is fine . No back history on this jeep . I've now found the heater blows barely warm & the ac blows barely cold . I've read many threads about blend door problems & clogged heater cores . The heater fan blows fine & switches to whatever vent I move the selector knob to . The air is barely warm when the heat / cold knob is turned to hot & blows cool when the knob is turned to cold . Both of the hoses going to the heater core get hot . Before I attack this problem I'd like to know if a blend door problem could cause a barely warm heater & a barely cool ac ? These could be two completely different problems but I'd like to know if one problem can cause both . The ac does have a charge in it . I have a recall notice that will require a visit to the dealership . Can the dealership check for proper operation of the blend door / doors with a scan tool ? How many blend doors are there ? TIA I know many people visit multiple forums but I'm going to post this on another forum anyway . |
