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: 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.

Remove cover[3 scews] unplug electrical connector. then remove the 3 bolts that hold the fan assembly in the housing. take motor apart and clean check brushes in brush holder, then sand the armature where the brushes ride. Stretch spring on brushes , the put the motor back together. works 95% of the time.

I have a 1984 cadillac deville small plastic piece inline with heater core hoses leaking ..at back of air filter on top...what is this piece called?


probably your heater control valve. below is a replacement from autozone, but yours may look different. If it isn't the control valve, maybe it's a splice someone put in. The control valve is the only thing that comes stock in the heater hose.

Wear is the heater valve located in a 95 cadillac deville


Hello, There is not a heater valve, the temperature of the heater output is controlled by directing the air flow either through or around the heater core or somewhere in between depending on what temperature you want. There are actuators on the passenger side attached to the programmer. Remove the glove box and lower closeout panel on the passenger side with key on change temp setting and they should move, the lower one is for the driver side. These actuators were a high failure item.
