Question about 1997 Pontiac Bonneville

Open Question

1997 Pontiac Bonneville Climate control System/Heater

When i try to set heater temp; whether manually or automatically, and the blower speed, it does not respond. It turns on and off when it wants, even when car is setting still. When the unit is working, there are no problems, the blower sounds good and temp. is fine. Is there any kind of programming in the system that could have messed up cause it seems like mechanically its working? Recently it hasn't been working at all. The settings are showing that it should be working but it isn't.

SOURCE: 2005 Pontiac Bonneville hvac blower does not come on

The blower on my 2005 Bonny GXP quit at about 60,000 miles (I really like using High). The blower is under the passenger dash. Mine had a three wire connector. The center wire should have 12 volts. It doesn't take very long to pull the fan out. Mine was toasted. Aftermarket fan was about $130.
See this website for my instructions:

SOURCE: 1997 Bonneville SSE, when the heater is turned on, only cold air

you may have a failed blend air door motor/actuator. this part will regulate the amount of air from the heater core depending on the temp setting on your electronic climate control unit. if it has failed, it will be stuck at the temp that it was last set at when it quit working. it is also possible the heater core may be plugged up, but using the gm recommended dexcool coolant and flushing it out every 5 years, it should not be plugged up. you can pull the 2 heater hoses off the heater core on the passenger side of the engine compartment firewall and see if the heater core is the problem. caution-do not use a high pressure air hose to blow through the heater core as this could damage it and cause a leak!

Heater fan runs when heater is off.06 ford expoler


Automatic or manual climate control ?
  • The blower motor does not operate correctly - manual climate control
  • Circuitry short
  • A/C blower motor resistor
  • A/C blower motor switch
  • Blower motor high speed relay
  • Go To Pinpoint Test O .

  • The blower motor does not operate correctly - EATC
  • Circuitry short/open
  • A/C blower motor speed control
  • EATC module
  • Go To Pinpoint Test Q .

Pinpoint Test Q: The Blower Motor Does Not Operate Correctly - EATC
Normal Operation Under normal operation, the blower motor control module receives a 1-2 volt signal from the EATC module through circuit CH218 (GN/VT) to determine the desired blower motor speed. The EATC module receives a feedback voltage from the blower motor control module through circuit VH219 (GY) to determine actual blower motor speed. When the highest blower motor setting is selected, the EATC module sends 12 volts to the blower control module through circuit CH217 (BN).
    Possible Causes
  • An open, short to voltage, ground or together in circuits CH218 (GN/VT), VH219 (GY) or circuit CH217 (BN)
  • Blower motor control module
  • EATC module
  • If automatic HVAC system i would suspect Blower motor control module .

1994 pontiac boneville blower fan motor dont work on high


Automatic or manual heater control. Automatic is the one where you set the temp to a certain degree and it maintains that temp. Manual has the temp control on a dial or levers.

Why wont my a/c or heater fan come on?


When the blower works only on the high setting its usually a bad blower resistor which is right near the blower motor. now you say it would always blow high regardless of the fan speed setting that would indicate probably the climate control unit or a connector problem somewhere. finally it not working at all may be the climate control unit or connection went bad even further. it might have a blown fuse or a bad blower motor in addition to the climate control unit or connector problem .check for power and ground at the blower motor. the power is supplied from fuses and may have a relay also. the ground is supplied from the climate control unit and goes through the resistor to control the fan speed. good luck

Good morning I am not able to locate the fuse for the heater can you help


First, please reviw this article: Where's the fuse?

Then, to answer your question: There are at least 3 fuses that have to do with your Heating/Air Conditioning system. There are also different fuses depending on whether your vehicle is equipped with Automatic or Manual climate controls. However, if you are referring to the main fuse for the blower motor, both systems use the same fuse and location. It is fuse #3 in the Underhood Fuse Block. It is a 30 Amp fuse.

I replaced my heater blower in my 2002 bonaville and it either wont work at all or it runs all the time and woont shut off


Does the car have a climate control system? Could be the heater/AC control or the associated sensors have a problem.
The other required part of the system are the heater resistors. These allow for speed control. They could cause intermittent behavior, but would never cause the fan to run all the time.

Blower fan runs high only on 2006 Ford Explorer


if you have manual control climate control then the system has a blower motor resistor . if you have automatic climate control then the system has a blower motor speed control. in eather case the part is under the dash in the heater box. depending on the system you have, buy the part and then look under the dash for like part, you will half to remove the under dash panels to be able to see. the part will be on the heater box somewhare.
