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: Engine overheating in 1999 Cadillac Deville.

The most common overheating problem with the Northstar engine is a blocked purge line(small hose).The purge line is designed to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank (not the cap) ,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.
If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.
The hose goes in to the engine to a crossover and comes out the other side close to the thermostat housing,the blockage may be there.

Also note that the cooling fans don't come on until the coolant temperature hits around 225 degrees.
During normal highway driving the fans will very rarely come on(if at all) due to constant air flow through the radiator.They will only usually come on in heavy traffic conditions on a hot day.
But......if you have the Air Con switched on, the fans will run all of the time.

Hi! My 1999 Cadillac Deville for about 2 weeks started messaging low refrig-ac-off. Check engine light on!.


When you change your oil is up to you,you set the
months & miles you go. Any car with a reminder
for oil is just a gadget

You were told that your low on a/c refrigerant by the
message

Now the check light related or not has to be addressed,
by checking for codes & diagnosing the effected system

Your a/c system needs repair,not added to, only to leak out
& polute the atmosphere

1999 cadillac deville 4.6 heater blowing cold air, set temp at 90 degrees


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...
