One more thing, that first day when the driver's side blew only hot, if I turned the AC on then you could feel that the AC was blowing and mixing with the hot air through the driver's vents. It doesn't matter whether it blows on the floor or dash or defroster, it's all cold for the driver.
Any suggestions as to where I should start looking/testing would be appreciated!

hello
you have a broken blend door its a common fault with grand cherokee's
if you remove the glove box you will be able to remove the motor which controls one of the blend door note there are to blend doors one for each side of the vehicle. remove the motor and see if youcan turn the spindle 360 deg if it does you will have to remove the heater box and strip it.
