SOURCE: 1999 cadillac deville air wont work

There's a blower motor (fan) under the hood and up against the firewall near the center of the car that takes some work to remove. It has gone out in the last 2 of my 4 Cadillacs. Turns out if you're not real careful with the positioning of the spark plug wires they will brush up against it, and if one of them gets cracked or brittle it will "arc" and short out the blower motor. The a/c compressor should still come on (you'll hear a click when it engages) but you won't get any air blowing into the cabin, hot or cold.

The part was like $200 stock (year 2000 prices) and it took about an hour to remove it. My Caddy at that time had this damn strut bar going across the engine bay which we eventually removed to get to the blower motor.

SOURCE: 1999 cadillac deville 4.6 heater blowing cold

Besure that you have enough coolant. Your engine has head bolt issues and this allows compression gases into the sooling system, and this pushes coolant out and the heater goes cold before the engine everheats.... VERY expensive to fix correctly. There is a test to determine if exhaust gases are in the cooling system...

How come when I start up my 1999 Cadillac deville I smell antifreeze real strong through the vents ? Is something wrong?


The heater core may be leaking / faulty - not familiar with Cadillacs, but normally it is located inside the car, behind the dashboard (glovebox) on the passenger side (near the blower motor). This may be something for a mechanic to diagnose if you are not familiar with automotive heating/cooling systems.

98 caddy deville nothstar v8 how to replace heater coil have no heat and I'm loosing water somewhere


the heater core in a 1998 Cadillac is very tricky to replace.
start with getting a pressure test to determine where the exact location of the leak is, it may not be the heater core.
if you do decide to pull the dash apart to change the core make sure the battery is disconnected for at least an hour to allow the airbag system to discharge.

Is your floor wet on the passenger side up front and smell like antifreeze? If so, the heater core blew, but it's not hard to replace.

My cadillac is not giving me any hot air ,ive replaced the radiator, changed the thermostat, has a new water pump, where do istart to look.


Feel the 2 tubes at the firewall for the heater core. If they are not getting hot, the heater core needs to be flushed out or replaced. I had this problem with a 1990 Cadilac Deville, it was just a plugged up heater core.

Remember to install sealant after flushing out the system to prevent leaks.
