Blows cold on passenger side, warm on drivers side
Air no longer works at dashboard, only windshield and maybe floor.
when heat on..cold air out of the passenger side
vents blow warm air for driver side, but not for passenger side; cold air when it should be warm from front defrost vents and from floor vents.
Air conditioner works but air coming from vents is erratic.
no hot or cold air from middle vents
cold air on drivers side when heat is turned on
cold air coming from drivers side vent while heat is on
Temperature blend actuator on drivers side failed, and replaced. Easy DIY fix for a handy guy. Now the actuator that selects between windshield, mid, and floor is out. Frosty windshield sidelined the Buick for the day... Now I need to hunt down that actuator and fix that one too. - Grandma Car - 15years and only 35K miles - expect a few age-related problems...
Cold air blows through driver side when the heater is on
1998 Buick Park Avenue 6 cylinders 3.8 The A/C doesn't work properly. Cool air blows on driver's side and hot air blows on passenger's side. There is also like a clumping sound like opening and closing a vent that occurs when the car is turned on. Checked the freon and it is fine.
A/C doesn't blow from the front of the dash/Vents. Only to floor vents and to windshield vents or both but not forward towards passengers via dash vents.
Ac blows from defroster and floor but not in the middle...
no air flow to the dash vents
only passenger side blows hot air
A/C blows cold from passenger side vents, warm from driver's side.
Blows heat drivers side cool air passenger side when a/c is on
A/C did not come out of mid. Got estimate next day it started working. Worked for two years now heat coming out of passenger side while ac is on. AC working fine on drivers side. How can I fix it?
Driver side warm air - passenger side cold air - rear center console vent (air) not working (no heat or air)
