Question about 1999 Cadillac DeVille
I have a 1999 Cadillac Seville and I need to know the location of the A/C Blower relay.
SOURCE: blower motor relay
there is not a relay , I had same problem and found out that its called a resister . the location is behind glove box , and to the left of the blower motor housing . look for a blue box with about 6 wires plugged into it . It has one screw holding it in , that the resister it is 39.99 @ auto zone and it will have to be ordered Please leave feed

replace the relay , when a relay sticks like that , a good test is to slap it with something like the handle of a screw driver , see if it un-sticks , its not a fix , just a test . cheers'

If the fuse is good,check to see if there is voltage to the blower motor,if there is,replace the blower motor.Sometimes,not always,if you bump the blower motor,it will start working,if this happens,then the blower motor is bad,if it does not,the fan switch could be bad,but the relay is usally near the blower motor.Testing it with a test light is the best way to test it,ground one end of the test light,the other end has a point on it.Use the piont of the test light to touch all the legs on the relay,with the key on,and the fan on high.The test light will light up,on almost all the legs,but it will also activate the relay when you touch the right leg of the relay,the relay needs to stay plugged up as you do this.If you can not access the legs of the relay,because of a skirt on the relay,push the point of the relay into the wire that you are testing,or into the plug,near the leg of the relay.The legs I am refuring to,are the prongs on the relay.If the relay clicks and turns the fan on,when you touch the right one,then the fan,and the relay are good,it will be the blower fan switch.Now if you already have high,blower fan,and the lower speeds are the problem,replace the blower resister,It is mounted right next to the blower motor,and has about 7 wires plugged into it.

if it works only on high speed you need a blower motor resistor you will find it close to the blower motor has three wire to it and looks like a small 1 inch by 3 inch piece of computer board material with two screws holding it.once you get it off you will find that one of the springs has lost contact.
