SOURCE: Ihave a 1992 caddy deville Ican hear the blower motor blowing .

I may have had a similar problem, for a long time my blower motor made a loud howling/roaring noise, hard to explain, but I only heard the noise when the blower was turned on. It continued to blow air for a couple years then just quit, the noise it made continued for another 6 months to a year without air-flow. Finally it quit blowing air at all. I eventually replaced the blower motor and no more noise and air flow was restored. Hopefully you already have fixed this because removing and replacing the blower motor wasn't fun.

SOURCE: 1999 cadillac deville blower dont

red black and gray are just half the connections. Red is positive 12 volts coming from fuse of circuit breaker. The black wire is either the ground or the main hot wire going to the blower motor (3 pin connection only), and the gray wire (if is is small in size) is a variable voltage coming from the body control module requesting speed for the blower motor.The blower control module varies voltage on the main wire going to the blower motor, supposedly in accordance with the requested voltage from the body control module. Usually if all fuses are okay and present on the apprpriate wire of the blower control module, the a blower motor that will not run or stays running after the key is turned off is the fault of the blower control module. If the blower control module has failed the the cause must be determined (over amping blower motor) or else new blower control module may fail when powered up.Usually blower control modules have more than three wires. Usual connections are: B+ (battery voltage) GND (chassis or engine ground), two large wires going directly to blower motor (can be any color, but are usually 10 guage in size), and an optional wire that reports voltage level back to the body control module.

Front blower/rear defog 15A fuse keeps blowing

There is a short to ground on that circuit (a power wire is touching a ground somewhere). Since it happens when you turn the heater on, it's most likely between the front blower and the fuse. Unfortunately there is no easy fix that won't burn your car down, you'll need a wiring diagram and a short finder or multi meter.

I have a 98 DeVille and the blower motor for the heater/AC doesn't work.

Hey Jeff,you did check fuse in fuse box on driver side,if good and secure,then it may be your blower motor resister,it's located by blower motor,controls the blower motor,if bad it won't run or just on some speeds,if part doesn't fix,Autozone will refund.You can't tell by looking at resister to see if bad.Here's a link to the blower motor resistor,

92 cadillac deville no heat or air blowing at all

Devilles use a controller instead of a basic blower resistor.
Someone would need to check the blower motor for power and ground, then check the controller mounted in the HVAC box on the firewall.
You may need a shop manual to get the wiring diagrams needed to troubleshoot the system.

.i installed a radio in

The wire that was for the alarm was a single wire that was grounded to the radio chasis, its a different color for 80's to 90's but if you know the one you took off to the old deck then just ground it somewhere on the outside of the new deck and you will be set.

Hi, the horn wire in the column is black. This is not a power wire, as the switch only supplies ground to the horn relay. Grounding this wire turns the relay on which blows the horns. Please let me know if you have more questions, and thanks for using FixYa.

I have three problems- I bought this car used. I was told that the blower motor for the ac/heater may be out. It definitely is. I discovered that it could either be a resistor or the blower motor itself....

Check the fuse or the circuit breaker.?Remove wires at the blower motor.One will be the ground wire,black,in color?? the other will be the hot.If there is only one then the motor is grounded by its mounting. Check wiring diagram.for colors or use an inline fuse 20 amps. in the power test lead Run a ground wire to the other. A premade set of test leads are very helpful.This will test the motor.The fuse may blow if the leads are reversed or the motor is shorted,or draws too much current.If motor tests ok,repair the open.Test the switch and the high speed relay,then the resistor packl All with finction of the blower switch.No slow speeds,bad resistor pack or switch,check resistor(visually),no high speed with switch?Bad highspeed relay. A wiring diagram will be of help,in checking points in the circuit where the color code is used.Without a diagram is a guessing game and takes more time.

Help! I have a 1969 ford mustand that when I turn

i guess you'll have to check wiring and the connectors. first, visually examine the wiring and connectors for signs of corrosion or missing insulation. corrosion can make a conductive path creating a short. if there's no visible signs of a fault, you have to obtain a multimeter. these can be very inexpensive. probably 10-20 dollars at radio shack. check the connector terminals for ground one at a time. insert one probe into the terminal and touch the other to a clean, bare metal boby part. one of the terminals will be ground, the other two should not be grounded. remove the negative battery terminal before you start. here's a wiring diagram. if the link doesn't work, go to register and enter your vehicle. go to repair guides and select wirng diagrams;jsessionid=1755830D3356BFBC0EF2FA08D7A913E2.diyprod2-b2c12?chapterTitle=Wiring+Diagrams&partName=Chassis+Electrical&pageId=0900c1528027a27b&partId=0900c1528027a1b9

Free wire diagram for horns on a 1972 corvette

The horn gets it's power from the horn fuse which is live all the time.Power goes from it to the switch and then out of the switch to the horn.Test the wire to the horn with a test light or a multi-meter and if there is no power you likely need the horn button replaced,if there is power you may need to remove the horns and clean the rust from their mounting points to get a better ground or turn the adjusting bolt on the horn until it will blow,if neither of these work you will need to buy a new horn.
