A co-worker of mine has a 90 Se and today he has noticed that there seems to be no heat. This is a first. Can anyone tell me if there is a quick check on this problem or should it be taken to the shop? A quick response would be appreciated.

Does the fan come on when you turn on the heat?

 

He didn't say. I would assume the fan blows, but never heats up. I know this information is limited and it is sometimes hard to diagnose problems with limited info. What is your thoughts?

 

Check the vacuum hoses that connect to the heater control valve. It is located under the hood, in the center, at the firewall, at the top.

 

Just this past Friday I had to remove my heater motor and clean it out. There was an excessive amount of leaves and dirt in it, I even removed the motor cover and cleaned it out. Works fine now, quiter too! I did have to remove the glove box, but that was easy and was done in about 10 minutes in a parking lot.

 

My 3rd Gen did this when I had it. The Heater core also burst at 100000km and spewed alover the ecu and fried it. I sold it after that.
