Radiator 95 olds aurora  
4.0L V8
dash lights = check engine
GM Computer codes = many 10
Repair work done prior = new water pump,thermostat,belt,upper lower hoses,radiator
Work done to repair this problem = none
GM tech = mw
question = upper driver side of radiator inside near air cleaner there is a hose coming
off it! Where dose it go and what dose it supply??? Mine is capped off with a bolt and a
hose clamp. in the winter the driver side would blow just cold and still dose! So i guess
my question is why dosen't the driver side have no heat or defrost just cold air
passenger side has good hot air upper and lower heat.






MW:
By what you are describing, this sounds as if the radiator has been replaced.  
Replacement radiators come with all possible fitting, depending on application. If a port  
/ fitting is not needed for the cars original setup, then it just gets plugged off. Nothing to
 worry about.
The above would have nothing to do with the heater, A/C problem. Most likely you have
 a faulty temperature door actuator motor under the dash for the malfunctioning side.
