20 Most Recent 1999 Pontiac Montana Questions & Answers


There should only be 1 bolt holding the arm in place and it should be accessible from the top side. Not exactly an easy process but doable.

Here's a video of process. Can't see a lot because of the camera angle and the confined area, but it should give you a general idea.

You can skip to approx. 6:20 to get to the actual extraction and 7:35 for the replacement if you don't want to hear all the general rambling.





Hope this helps.

More likely a fuel system problem starving the engine - particularly the fuel pump. Check the whole system (lines, pump, filter, fuel pressure, etc.).

get a pressure test on radiator via a radiator cap that has a pressure gauge with the engine running . The head gasket is probably blown on the engine and this can cause exhaust pressure to go into the cooling system and create this symptom you are experiencing.
you may also have more expensive problems like a warped head or cracked head . $$$$$ - remachining or welding and remachining of engine head and a blown gasket .

The starting /keep running issue is probably a slow IAC (idle air control)Next time turn the key on,wait 3 or 4 seconds then start,if it keeps running after that wait time everytime,it most likely is the IAC,,,,,,no big deal.

The radiator may be plugged or the head gasket can let compression gasses into the radiator . To check, run the engine without the radiator cap and look in to see if there any bubbles in the coolant. If there is a lot of coolant moving in the radiator after the T/stat has opened, the water pump is ok. If not then suspect the water pump is not circulating enough water.

Park lamp fuse 20amp located in the under hood fuse box .DRL control module
Daytime Running Lamps (DRL) Control Module
Right of the steering column, behind the IP
Park, Sidemarker, Tail and License Lamps
Voltage is applied continuously to the PARK fuse to the headlamp and the instrument panel (IP) lamp dimmer switch through CKT 1340.
When the headlamp and the (IP) lamp dimmer switch is in the PARK or HEAD position, voltage is applied to CKT 9 thus activating the following lamps:
• The park lamps
• The side marker lamps
• The tail lamps
• The license lamps
The park/turn lamps are the only lamps that do not activate yet receive a current from CKT 9. The park/turn lamps do not activate because the voltage drop across the front side marker lamps is much higher than that across the turn lamp filaments Step

You probably have a short or a loose wire. This is likely what caused the fuse to blow in the first place.

Recommended GM DEXRON® VI, Low viscosity transmission fluid.
Note: make sure you don't over fill transmission and the Montana's transmission are know for failures due to high fluid retention caused by high viscosity transmission fluid from additives or dirty transmission oil and filter.
Thank you for using Fixya and good luck.

I would recommend you check the fuel for contaminates.
Change fuel filter and flush carb.

You can try performing a diagnostic self-test of the DIC.

In order to perform the diagnostic self-test and reset the driver information display, simultaneously press the following buttons for at least 2 seconds :

MODE
ENGLISH/METRIC
The reset is acknowledged with the display showing all segments ON for 1 second . You may only reset the following modes. The reset affects all 3 of these modes simultaneously:

AVG ECON
FUEL USED
AVG SPEED

If all of the segments light as described above, but the same symptoms are still present follow these instructions:

Symptom: Driver Information Center (DIC) Always Displays Dashes

1. Check for a poor connection or an open in circuit 800 (Tan wire) between the DIC connector terminal 15 and the Powertrain Control Module (PCM) connector C1 terminal 15.
2. If a problem is found with the circuit in step 1, repair the circuit and retest. Otherwise continue to step 3.
3. Replace the DIC and retest

key FOB has a bad switch so you have to find a new one. New one will need the micro switches matched to the old one.
