Previous post: Cold air out the driver's side footwell, hot air on the passenger's side.

I was POSITIVE I had something wrong with a blend door or some other obstruction. I was certain the heater core was ok since, after all, I was getting hot air on the passenger's side. How in blazes does air "divide" itself into hot and cold after going tru the core?????

So, I spent a couple hours in various yoga positions disassembling my dash and winding my a-- and scratching my watch with nothing obvious to me.

Then, "Ranger" said, "flush the heater core because if partially plugged, air can stratify and cause this problem".

OK, so he's crazy.........

NOT!!!! I flushed the heater core this morning and GUESS WHAT? Ranger was right!!!! I've got +140 degree air out both sides!!!!

Ranger, thanks!

ranger is da shit isnt he

Ranger, thanks! :thumbsup: Glad it worked.

yeah Ranger . props to you man!.

BTW, what did the coolant that you flushed look like? I suspect there was a lot of sediment or sealant tab residue.

Hey Ranger Will This Work If I Get Hot Air From Driver Side Vent When Ac On And Cold On Passenger Side?

Re air cond: Father in Law had the same A/C problem: warm on one side, cold on the other. Dealersaid it was low on refrig. FIL said dealer was full of bull! Couldn't happen. Dearler said "trust me".

Recharged the A/C and voila! cold air out both sides! Go figure?????

Yea, differential temps with A/C on is a symptom of low refrigerant in a dual zone system.

I just had it recharged this past summer..But Ill have to get it checked again!!
