2001 Pontiac Montana Questions & Answers
Will 195-60r15 fit on my 2001 Pontiac Montana
The original tire size is 215/70R15 and you're asking for 195/60R15.
According to tire size chart, you are more than 3% diff overall size diameter. So if you drive your van at 60km/h your speedometer will read 54.1km/h.
I would say no it won't fit without changing the speedometer reading.
Hope it helps.
2001 Pontiac Montana Rear heat blows only cold air???
The rear temp blend door is stuck in the cold position ,very common problem on vehicles with rear HVAC units . There is no valve , electric actuator !
Air Temperature Actuator
The air temperature actuator is a 3 wire bi-directional electric motor. Ignition 3 voltage, ground and control circuits enable the actuator to operate. The control circuit uses a 0-12 volt linear-ramped signal to command the actuator movement. The 0 and 12 volt control values represent the opposite limits of the actuator range of motion. The values in between 0-12 volts correspond to the positions between the limits.
When the HVAC control module sets a commanded, or targeted, value, the control signal is set to a value between 0-12 volts. The actuator shaft rotates until the commanded position is reached. The module will maintain the control value until a new commanded value is needed.

Low/high side A/C compression reads the same
Why was the compressor diagnosed bad?Did it send anything into the system that may have blocked a line?Did you flush the complete system?
I would have started the compressor by jumping the low side switch to make sure it could pull a good vacuum before adding any 134a.
You may have a blocked system with debris/grindings from the old compressor?
The replacement expansion tubes may be blocked now,were the old ones clean?
Make sure you have good air flow through the condenser when refilling the system.
Does the new compressor sound like it's working correctly?
I still want to see it pull a good vacuum first.
2001 Pontiac Montana. Van overheats
Where do you
hear a valve or flapper moving??? Behind the dash ( instrument panel ) It sounds to like you have a electrical problem , not overheating problem . You need to test to see what the real engine temp. is . Also have vehicle checked for DTC'S - diagnostic trouble codes ,Sounds like A/C is kicking on , the flaper noise you hear is probably the temp actuator inside the dash . You can buy the tool in the video at harbor freight cheap. Point it at upper radiator hose ,near the engine . The IPC illuminates the hot coolant temperature indicator in the message center when the IPC determines that the coolant temperature is greater than 128°C (262°F). The IPC receives a class 2 message from the PCM indicating the coolant temperature.
Are you getting any such message ?
How to Use an Infrared Thermometer to Diagnose Car Problems
I have a whistle or humming noise from the front of 05 Montana.
Put wide tape on different areas of the windshield edge as a test to see if the noise changes.Then you may know where the noise originates and can correct the noise.
Just by chance,it is a wind noise? and not a front wheel bearing going bad?which is common on these vehicles and can create a humming at different speeds.Next time when the hum shows up turn the steering wheel slightly left and right at road speed and if you can change the hum,it's 99% a wheel bearing.
