Question about 1999 Oldsmobile Silhouette

1 Answer

1999 Oldsmobile Silouette Minivan-The A C blower will not go to maximum level. The blower motor will work on speeds 1 through 5. But it use too blow on a higher speed other than 5 when you hit the inside air circulating button, and now it is not doing it. I replaced the resistor switch. I checked the fuse 30A for the high speed 5 and it is working. What else could it be?

My 1999 alero fan will not work.I have replaced the blower motor and checked fuses and still nothing.The heat and air are working fine just not blowing.

Its either a bad connection on the blower motor resistor or a faulty blower motor resistor.These are known for over heating.

Blower speed question (ac/heater). This just

This is definitely 100% the Blower Motor Resistor.
Replace this and all speeds will work fine.
This Resistor is defined with 3 to 4 wires going into it, and is located adjacent to the Blower Motor.
It is easily access, removed and replaced.
I will post an additional comment on Part Number, Price and where available.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at!

of the blower motor makes a howling or grinding noise the motor is going bad. blower control modules are common and will not give you all the blower speeds.

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.

1999 town car blower motor resistor.....maybe?

The Blower Motor Resistor is a common problem in your car but not for the problem you describe. When the Heat/AC won't blow on all speeds, the blower motor resistor is at fault. When air won't blow out of vents, bi-level, or floor the problem is the blend door actuator. This is vacuum driven and diverts the air to where you select. When air will only blow from one place (usually the defrost) then the blend door actuator is the problem. This can sometimes be corrected if there's a vacuum leak (usually under the hood in front of the passenger you'll find the vacuum line and can trace it backward to find a leak). If no leak can be found, the blend door actuator itself is defective and needs replacement.

Switch for blower motor for heat & ac

Sounds like you need a blower motor resistor. It has bad paths between the 1 and 2 speed circuits.

AC fan doesn't work

Alright when it only works on high speed, then usually the resistor between the controls and the blower motor is bad because the default if on is at high speed so I would replace that first since it is much cheaper than replacing the blower, then if the blower is still making a bad noise, it is wearing out and needs to be replaced too. Both of these parts are under the dash on the passenger side. If you want a diagram, then I advise buying a Chilton or a Haynes manual from a local auto parts store especially if you plan on fixing it yourself. Let me know if you have any further questions.

1999 chrysler minivan- replacing front heater blower motor

I replaced the blower motor on my 98 and no, you don't have to pull the dash. You need to get under the dash so you will be pulling out the glove box. From there you start removing the screws on the blower motor housing (big round plastic piece) and then unhook the electrical connections and then the motor. Before you do all that, what have you done to confirm it's the motor? Does it only blow on one speed? If so, it may not be the motor but an easier fix - the resistor.

Hope you've been doing a few crunches to build up the abdominal muscles as it's a tight fit to get into this area and it takes a few contortions to work in there.
