1992 500SEL - Rear Vents
I installed an evaporator core on a '92 500 SEL due to leakage. All went well with the job except only cold air flows out of center rear vents under the armrest. Does anyone know if warm air is supposed to come out of these vents. My customer tells me the air is supposed to be warm. On BMWs - my strength in auto repair, this air flows cold. Mercedes is not my specialty and I wonder if anyone can shed some light. If it is supposed to flow warm, what is the fix?
