Well Adam got another control box from $hawn that I put on this morning along with a new fan motor and with the engine cold the fan comes on when the ac is on and goes off when its turned off----that seems ok but when the engine gets hot (with the ac off) I have no fan unless I unplug the sender thats located on the heater hose just befor it goes thru the firewall, the fan stays on all the time like its a belt driven one and goes off when the engine is shut off, so now the fan is on all the time the car is running, I have no problem with this but I would like to have it operate like it should ,any idears why this is working this way?????thanks Al
