You can get to the switch from under the car on the left side.) 1) Start the engine. If the fans are running all the time they will be running now. 2) Slide under the left rear of the car, where you can see the thermal coolant fan switch. 3) Disconnect one of the two wire that are plugged into the thermal coolant fan switch. 4) If the fans cut off at this point the switch is your problem. (There is also a diagram of this on my web site. http://stainlesssteel.freeyellow.com/index.html ------------------------------------------------------------------- It should be noted that I had received new sending units that would only work for about three days.....I cured this problem when I found a OEM sending unit. Don't know if the venders have cured this problem or not. The Volvo sending unit setting are a little to cool for the Delorean but it will work, only problem is that the fans will run a little longer. If you require any additional information contact me by e-mail. (address is on my site.) Robert Starling Vin#5252
