1999 olds intrigue blower motor broke again after being replaced

My blower stopped working on any speed 6 months ago. I had it and the resistor replaced yesterday and after it was "fixed" it "blew" and stopped working. the mechanic replaced the motor at no extra charge and told me of the occurence and hypothesized that the problem may have been the blower modulator causing a spike in voltage. He claimed he had checked and couldn't find any spikes but wanted me to know in case it reoccurred. As I was driving home the heater blower was working fine and then I heard a "pop" the blower still works but I called the mechanic and he said when it broke for him he heard the same thing and it stopped working completely. Does his suggestion sound reasonable and if so what might it cost me since I have already spent $500 for the above repair and a new battery?

SOURCE: rpm`s spike up and down

I don't wanna laugh but the Vibration of the defrost is probaly wiggling a connection --most likely a harness ground on the engine bay firewall ---I'd check the grounds then the throttle position sensor connector connection and then the --Don't laugh distributor connections to inlude the engine to cab ground cable ---braided bare cable from the block to the firewall -

--the COIL pack may have a poor connection ---and I believe if correct on blazers the feed wire to the coil from the harness
is thick and pinkish that connection if loose describes the symptoms exactly

nothing works without a sufficient GOOD gound --loosen and retighten and ground wires-positive wires and connections ----GM is well known for wiring harness problems ---my 84 blazer
happened to share the same ground for the Blower motor and the distributor ---not anymore!
check your connections and those grounds --am I repeating myself ---and also continue to seek help in here if still persisting after that ---should only take 15 minutes to check it all
30 to fix most likely
hope this helps

SOURCE: 2000 Olds Alero. Cooling/Heating fan stopped

The blower is on the right hand side under the dash. You are right in thinking the blower resistor is the problem. The resistor is in the heater box behind the blower. Only 2 bolts hold it in but the back one can be a challenge to remove. The bolt is 5.5 mm.

Check for power and ground with a test light at the resistor connector. You should have power on the colored wires in the various switch positions. The black one is ground.

Blower fan control problem

Check the wiring to the motor and resistor pack For the motor to run at full speed all the time indicates that there is uncontrolled voltage to it which means that there is a earth after the motor before the resistor. For the resistor to burn out .Well it requires fan air flow to keep it cool and with the ignition off it must still be getting current to it to earth. I am suspecting a faulty automatic control module. I suggest you have it check out for failure.

Follow the blower wires back to the resistor, which is screwed into the heater box. Remove the resistor and check for heat damage and continuity. Most likely it is burned up. The assembly also contains a relay, which is usually only used for high speed. The assembly is $32 at autozone.See pic below.

The blower motor fan is controlled by the blower motor resistor.Its the resistor which controls the fan on respective speed which you select.But if the resistor goes faulty,then it will not be able to set the required speed which you set for fan,so it works on high speed only. In this case you will have to replace the blower motor resistor. Check fog for the location of blower motor resistor location:--- see part number 8 in the diagram below. helpmech_11.gif

The blower motor resistor is located next to blower motor under the dash.Its fitted with 2 screws and a wiring connector.You have to remove the screws and wiring connector and take the resistor out and place the new resistor in same position and connect the connector as well as screws. ------------------- this should help.Thanks.Helpmech.

The heater switch stopped working - could this be a fuse or is the unit replaceable?

Yes, check the fuse first. Make sure that none of the blower speeds work, a common failure is heater blower resistors that cause one or more speeds to stop working.
Next, it is just as likely or more that the blower motor itself has failed or is stuck.

99 Olds intrigue heater fan now only has 1 speed(high). Would this be the fan or the heater control panel?

I just did this fix to mine. It is the blower motor resistor that is located between the fan motor and the firewall. You will have to remove the trim panel, under the dash. Then you will be able to remove the fan motor. The fan plugs directly into the resistor. You can get the part at checker for about $32.

Heater blower motor speed control problem. I installed a new heater blower motor. When turning key on motor blows hard for about 3 seconds then stops then comes on again for 2 seconds. Then drops down to...

sounds to me like you have a resistance switch problem. The old cars had springs, i. e. resistors to control the speed of the motor. newer vehicles have electronic controlers, they can be very sensitive to corosion. first check the plug the replace the switch.

Replaced blower motor, now runs continuously.

Run's continuously ? High speed , low , med 1,2, 3 . ????
Probably the high speed relay contact's stuck closed . The fuse for the high blower is hot at all times , low blower fuse is hot only with key on. It sparks becaused the motor turns on . If it had a short the fuse would blow . The blower motor relay is part of the resistor pack near the blower motor .

99 Olds Intrigue, blower fan resistor

It will burn out. Air flow in the heater box cools the resistor. These resistors get very hot when the blower is running.
