SOURCE: 1999 Caddy Deville A/C problem

A/C systems are hard to diagnose without having access to the vehicle. One of the most common problems is undercharge (Not enough freon in the system) indicating a leak somewhere in the system. Other causes could be a burnt A/C compressor clutch fuse, defective compressor clutch, defective compressor/belt, defective High/Low pressure switches in the system, defective evaporator icing switch, defective wiring... Basically, you're better off getting the system diagnosed by a good A/C knowledgeable mechanic...

SOURCE: fuel filter replacement 1993 Cadillac Deville

hello. it should be located under your car on a line that's coming off your fuel tank and yes you can do this your self very easy to do ,you'll need a few box/open ended wrenches that's it you'll need to check the fitting or the nut on each side of the filter to see what the sizes are,befor removing the filter you'll want to take off your gas cap and remove your neg battery cable ,not when you find the filter it'll have nut on each side all you have to do it loosen them but make sure that you don't break the fuel line or kink it and after you have both sides loose then just finish turning them off and there you go the filter is off, nope no removing the gas tank some newer models you do and the filter is attached to your fuel pump and don't need replaced but for your car and year you wont need to remove the tank. good luck

SOURCE: 98 cadillac deville battery wont hold a charge

sounds like a 12V drain on the system, like a trunk or glove box light that won't shut off.> Could be many. many other reasons why. The way I would find the draining circuit would be to remove the neg cable of the battery. I then would connect a 12V test light between the neg battery TERMINAL and the neg battery CABLE. With a 12V drain the light will shine. I would install into the light a 9V battery powered recepticle to hold computer and radio station memory. Then I remove fuses 1 at a time, then reinstall, at the same time looking for the 12V light to go out. Hope this helps.

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.

2002 deville cadillac gas gauge changes level of gas at times when i have driven just a mile or two


You need to replace your fuel level sensor. But previous post is right, if you're comfortable running based on fuel remaining and kilometers, don't sweat it. If you're keen, the fuel level sensor can be accessed from the trunk (under the liner on the passenger side, beneath the silver panel).

Hi!!

You may have a defective fuel level sendigng unit or wiring. It should be part of the warranty coverage. Check with your friendly dealer :)

Runs out of gas but still shows 5 gallons


It sounds like your fuel sensor is faulty. I've seen this happen quite often with GM vehicles.

91 deville fuel gauge flashes "E"


It seems that you are low on fuel based on you saying 70 miles in the range gauge. If this problem does not happen with 3 gallons of fuel or more then it is normal. The range is calculated on your average MPG and gallons of fuel in the tank. When the car gets to around 2 gallons it does not chance miscalculating your miles to empty and leave you on the side of the road. At this point he tank will read "E" to let you know it is time to fuel up. The flashing "E" is simply cadillac's way to get your attention that you are in fact low on fuel and need to take action. Hope this helps.
