I have a 1998 bonneville that has climate control when i have the air/heat on high or recurlate it shuts off. After only a few minutes. I have had the ac condensor changed and the freon drained and recharged. I also changed the blower motor and the plug that plugs in to it. the plug had gotten hot and was out of shape and crumbly. Any body have any ideas where to look next any help would be aprecated. Thanks Tony
