Hello all,


I have a 1993 Buick LeSabre Limited that is having some defroster issues.


The car has the electronic climate control with the passenger climate control aswell. When I start the car, the main climate control center temperature display flashes for about one minute, then goes steady. With the temperature at 90 degrees (max) the car will blow hot air out of the heater vents but not out of the defrosters. What would cause this?


Any answers would be appreciated.


Thanks
