I am driving Nissan altima 95 with 170k in mileage. The problem I am having here is my aircond not working. Each time when I turn on the air con, the air is not cold. There is hot air. I checked the line and found the air con line were very hot. Why and what should I do the get this fixed? Secondly air con selector switch only works when I turn the indication to number 4. There be no air coming when I put at other than number 4 selection. I changed new selector switch yet still same problem incur. Kindly advice
you need to go to an AC service and have it looked at. The fan motor probably has all the resistors burned out for the lower speeds. Get a repair manual and it may show you were they are if you can replace them
