Not sure if Im using the right verbage. Car is equiped with driver/passenger climate control. I just took a short trip with my mom and she is FREEZING to death. Passenger side is functioning correctly. Driver side blows air fine but no heat.
I just learned of this and wont even be able to check fuses let alone mess with it for several days.
Any input regarding the dual climate control setup or this issue in particular will be very much appreciated. I dont have a service manual for car either.
Check the coolant. No heat is a sign of low coolant or possibly air in the system. If its low, try to find any leaks as those will need to be addressed. Top up the fluid ensuring you stay with te same type of coolant that's already in the car. If you have to top t up make sure you bleed the coolant system. One good idea some people recommend is to lift the car a few inches to help the air get to the top.
Thanks for reply. I have been checking oil and coolant on this car bi-weekly for 3 years. No problem with the coolant or its level. As I shared in first post passenger side of dual climate control works fine, max setting is 90f and it will cook your feet. Driver side does not have heat. Adjusting the fan output services both dirver and passenger side equally. But dirver and passenger each have thier own temp control.
I hope to get out there this evening and check fuses. At this point that is all I can do.
Don't waist your time with fuses. A blown fuse would not allow you to have any heat not matter passenger or driver side. I would focus you attention on the doors. You have power, You have Heat, You have air flow. Your problem is not getting heat to the correct location. I would go with 70marlin suggestions.
