[&:] Hey Guys! I'm new to the site but not to Caddy's. I recently bought an exceptionally clean 1993 Sedan Deville with 65,000 miles. It's in great condition. However, I notice that it does not get as warm in the car as I did in my '94 Seville. I replaced the thermostat, but it did'nt seem to make a great difference. On 90 degrees in my Seville, you would roast. In my deville it doesn't seem that warm. Any suggestions?

 

Put year and type of Cadillac in your profile signature. Lack of interior heat is probably a partially plugged heater core. Try back flushing. And what degree thermostat did you install?
