1990 cadillac eldorado blows out warn air no heat


Asked by Dec 19, 2014 at 10:34 PM about the 1990 Cadillac Eldorado Base Coupe

Question type: Maintenance & Repair

1 Answer


Assuming all else is working correctly - I would suggest checking to make sure a thermostat is installed. If so, make sure is the right temperature rating for that engine. The other check would be to make sure the coolant is circulating thru the heater core. At 24 years old - it may well be clogged.
