You might try looking at http:\\caraudiohelp.co There is a world of info there. Good luck.
Yes. All sunroofs both factory and aftermarket have drains because it is impractical to totally seal a roof opening.
Is coolant up to level? Are heater control cables functioning to their full travel Thermostat may be defective and opening too soon. Heater maybe either "airbound" and need to be bled or may be plugged
Low coolant? Cooling fan not working? Defective water pump? System airbound? Thermostat not opening? Hoses collapsing under pressure Radiator plugged or flow restricted? Defective radiator cap?
Same as most cars. You need a dash kit to adapt the DIN size aftermarket radio to the GM DIN and a half opening, then you need the appropriate wiring adapter so the plug from the aftermarket unit can plug into the Lumina's plug.
I believe it was a Pontiac
check your relays
I'm not positive on '89s but on '90s (I'm almost positive they're the same engine) its on the passenger's side. You should be able to see it by opening the hood. Its right next to the intake plenum/manifold and it has a pipe that connects just behind the throttle body. Hope that helps!
The drain plug should be located on the lower right corner of the radiator, it is about the size of a nickel with raised ribs that form a cross. You should attach a rubber hose to the radiator drain before opening the drain plug, this keeps antifreeze from splashing out. Antifreeze is a corrosive, that will burn your skin, and destroy your body paint.
No coolant Thermostat not opening Defective temperature sensor
If the 1999 Pontiac Montana glove box will not open with the key, there is probably something stuck in the latch, preventing it from opening. There is also a possibility that the lock was changed by a previous owner if the vehicle was purchased used.
It doesn't matter. A thermostat is a non-serviceable item. If it is bad, you replace it. That probably isn't your problem though.
You can open the trunk, by opening the glove compartment... there should be a yellow botton in it to the left after opening (inside) just press and it should open it. That's where mind's is on my 97. Hope this helps
