Odd warning light in dash for 2003 pontiac montana

We do not have manual for our vehicle, to find out what this certain warning light would indicate. this light, as well as the parking brake light come on very intermittently. we have checked that the brake is disengaged. the odd light is red background, with what looks like a wavy sea ????

When the wavy light is on with parenthasis around it and at the same time the (!) and (P) lights are on, this indicates a serious brake concern

I just had this same problem. I have no coolant problem.
I hit a pothole and my front end was damaged. Upon closer inspection the sensor was broken off and hanging down. If you seem to have no problems with your vehicle running properly, it may well be you have a damaged sensor registering a problem that doesn't exist.

A red background wavy sea light means low coolant.

2003 Pontiac Montana starter solenoid or relay location?

What exactly does it do when you turn the Key? Are there any dashboard lights staying on that normally go out when you turn the key to position 2?
Does it do absolutely 'Nothing' with the dash lights staying on? Does it do nothing but the dash lights go off?
Dash lights go off and you get a 'Clunk' noise?
Absolutely nothing suggests security system or the actual ignition key/barrel. This often has a light on the dash shaped like a key. Nothing but the lights go off could be the starter solenoid. Lights of and a 'clunk' could possibly be the starter itself.
The solenoid will be bolted directly to the starter motor. It's the smaller barrel shaped section on the side of the actual starter motor.

Fog Lamps The fog lamps switch is located in the instrument panel switchbank. Push the fog lamp symbol on the switch to turn on the lamps. The indicator light will glow.

While driving down the road in my 2003 pontiac montana. The change oil light comes on and high temp warning light comes on. When the high temp light comes on the van losses all power.

Check the coolant first. Add as needed. Once full. heat it up in the driveway and check for leaks. 3.4 montana, I would guess the water pump. Change the T stat also.

How to reset the computer on a 2002 pontiac montana

Which computer are you wanting to reset? There are at least 5 on your vehicle. The next question is WHY do you want to reset it? Are you trying to clear fault codes or are you wanting to clear adaptive learning stategies? or BOTH? Are you having a problem with warning lights coming on? If so, have the problems been corrected that CAUSED the lights to come on?

Anyway, a scan tool is required to reset ANY of the computers on your vehicle.
