Pontiac Montana Van Service Manual

Pontiac Montana (1999 - 2005) The Pontiac Montana started life as a trim level of the Pontiac Trans Sport minivan in 1997, but continued as a standalone model after the demise of the Trans Sport in 1998. It was offered in both short- and long-wheelbase forms and offered the convenience of sliding rear doors. It was powered by a popular 3.4-liter V6 gasoline engine, so spares are not difficult to find.

A crash test video of the 1997 Pontiac Trans Sport, demonstrated that it suffered extreme damage in the 40mph frontal impact, to the extent that the dummy’s foot was severed. At Haynes, we have an extensive range of repair manuals and online maintenance procedures available for professional mechanics and DIY car enthusiasts. Our Pontiac Montana repair manual is here to help you through every stage of servicing or fixing your car. Step-by-step maintenance and repairs guides for your vehicle in two formats.

If the wipers operate normally at high speed, the most likely cause is the switch. This probably means replacing the entire turn signal cruise control wiper switch assembly.

(the entire stalk and harness) You will need to rule-out a bad motor first by hot-wiring the motor to see if it runs in the low and intermittent speeds. You should use a schematic to identify the terminals on the motor before attempting to hot wire it. You can also use a test light at the motor connector to see if power is being supplied at the motor connector by the wiper switch. ( Iam not sure if the intermittent feature is controlled at the switch or in the motor itself but the schematic should show this) Shematics can be found in repair manuals at parts stores. Could also be the pulse control circuit board which is part of the motor assembly.

The whole Motor assembly can be replaced for under $150. First Troubleshoot the switch and hot wire the motor as indicated in the earlier message. Some Libraries have manuals either books or on-line tools like Alldata-DIY. Good Luck I had this problem. First test the control switches. I got an electrical schematic from alldata at my local Library.

You need a volt meter to check the operation of the control switch. First, Remove the wiper arm cover. A long triangle looking piece of plastic just below the wipers on Lt side (when facing the car) It comes about 1/2 way across the engine compartment. Second, disconnect the Wiper motor connector.

(you have to disconnect both the front and rear washer motor connectors to get this one off) It is located near the fill spout of the washer tank (Left side of engine compartment). Third, Have an assistant sit in the car and operate the wiper controls. Have assistant turn ignition to 'accy' don't start! With wiper control on 'off' Measure voltage from Black wire of connector to Dark Green wire. There should be 0 volts (or just a few mv). Have assistant turn wiper control to 'lo' Measure voltage from Black wire to Dark green Wire. There should be 10 to 12VDC measured.

Do the same with the Purple wire first on 'off' then on 'Hi'. You can also measure between the Grey and black wires first off then Hi or Lo should show about - 11.5 - 12V, As your assistant moves the controls to the longest delay the voltage should go down - at the lowest delay setting you should measure about 10.5 V. If you get these reading you are pretty much assured that the switches are good - And you should be very happy because if they are bad - it is about a $450.00 part plus 1.5 hours of labor - I would not recommend DIY. Turn the ignition off!

Now all you have to do is replace the wiper motor. I bought a remanufactured one at NAPA for $91.00 + a $27.00 core that was refunded when I returned the old one.

Make sure the wiper arms are in the park position! Test banks solution review. You need a TORX bit and a driver that can fit under the body - one of the screws (back Left) is hard to get. I had to use the torx bit and a channel lock to reach it. There are 4 screws. Take the one holding the control arms off first and pry up the control arm assembly. Clean it off well and re-lubricate it.

Remove the other 3 and slide the motor assembly out. When replacing it make sure you put the 'park' arm 'V' on the back tab. I took a picture with a digital camera before pulling the arm off just to make sure I got it right when reassembling.

(this little arm is hard to see - it is under the control arm assembly on the left - The 'V' fits on the back corner of the tab). Note: The motor comes preset in the Park mode. DO NOT RUN THE MOTOR PRIOR TO CONNECTING IT AND SETTING THE 'PARK' ARM CORRECTLY. Install it and then reconnect the electrical connectors to the wiper motor and to the washer motors. Put the ignition in 'accy' and try the wipers! Answer: You can get to them by removing the upper engine mounts and using a special tool to pull the engien forward, or with van up in the air, remove the exhaust pipe, lower the rear of the frame about 3-4 inches- while supporting it with a jack or the engine and trans.

And frame will drop and cause major damage. Now you can get to the plugs with a socket and ratchet. Do not recomend trying doing this yourself, unless you have the proper tools.- TechJK. You will need it on a lift and have several long extensions and a swivel. First thing to do is to check that the automatic door opening function has not been accidentally turned off. There are a row of toggle switches for various functions adjacent to the dome light in the headliner near the rear view mirror.

Van

One of these toggles turns the auto door on and off. Sometimes kids can get to this and toggle it by accident. If you can't determine which switch is associated with the door by looking at the image on the button check the owners manual for description. If you have checked the on/off toggle switch and it is 'on' but the door still does not open/shut automatically try this solution:. Disconnect the positive batter cable for a few min.
