all cars with Hvac, same answer an newer more.
V6 engine?
all fuses good
the blend door motor or controls are bad./
but wait car is 21years old wana bet 2 or 3 things wrong.
what year did heat or AC cold ever work rigth.
what I do is on blow high.
I fix heat first. as that can fix AC next. see and is far less work.
1: fuses good. all.
2: make sure engine coolant hits 180f first or more if not the thermostat is NO GOOD ,7 year live and is 3x that now,???
3: all that good I put my hands then on the 2 heater core hose and both are to hot to hold there
hand flies off. or TODAY for 10 years now mY
IR gun $15 shows 180f on both hoses for sure hot and same. if not core needs to be flushed, I use hose garden there,.
4: ok dampers are bad.
easy no?, get heat first.
the damper may becalled the blend door, and can stick in any wrong position, even half cold and hot, so both fail.
ac on , ac compressor spins due to clutch there engaged.
let me now see your dampers, I bet are not cable drive. (NOT )
but motors. yes! (Drive + gears)
$15 motor, +door
the cheezy door is plastic, and its axle too and they can break.
no fun ever that last one.
5 doors in this beast, recirc door must close for sure AC cold wanted.
check out this drawing,.
A AND B MUST WORK RIGHT FIRST.
for sure B is bad, IMO.
