You might have a blocked heater matrix and just some coolant is gooing through and not enought for instant heat.
don't think so,left side heats very well&quickly, seems like outside air is entering system for awhile then gets shut off & I get heat then
Might be as well a problem with the motor operating the right side vents and temperature if you have dual aircon
I'm Having this problem with my 2011 Dodge Avenger right now. What did you find to be the problem?
