Unfortunately, the entire instrument panel has to be remove on this vehicle. It is not a very pleasant job and requires a good mechanic roughly 8 - 10 hrs. to perform with the proper equipment.
Are you sure you want to tackle this?
Let me know.

Heater core leaking


Must replace the heater core. Its usually a very hard job that requires disassembly of the dash. If you insist on doing the job yourself, I suggest getting a repair manual from your local auto parts store so you can use it as a reference as you work. Here is a link to a video on a 98, yours will be very similar: http://www.youtube.com/results?search_query=1991+Pontiac+Bonneville+heater+core+replacement&sm=12

How do i take the dashboard off of a 1999 pontiac bonneville? have no clue where bolt are or wires to be unhooked?


Don't do that.
You always access components from underneath, and almost never take out the whole dashboard.
About the only reason I know of would be for heater core replacement in a car with AC, and I don't recommend that for most people.
Tell us more what you wish to accomplish, and we can give better advice.

1997 Bonneville SSE, when the heater is turned on, only cold air


you may have a failed blend air door motor/actuator. this part will regulate the amount of air from the heater core depending on the temp setting on your electronic climate control unit. if it has failed, it will be stuck at the temp that it was last set at when it quit working. it is also possible the heater core may be plugged up, but using the gm recommended dexcool coolant and flushing it out every 5 years, it should not be plugged up. you can pull the 2 heater hoses off the heater core on the passenger side of the engine compartment firewall and see if the heater core is the problem. caution-do not use a high pressure air hose to blow through the heater core as this could damage it and cause a leak!

1992 Pontiac Bonneville SE, steam in passenger compartment?


You need a heater core for starters...probally could use a full system flush also. Check condition of all hoses and replace as needed....also check radiator condition and replace if necessay. I have found that once one problem occurs in the cooling system it's a good idea to make sure everything is in good shape or you will wind up chasing leaks everywhere...good luck...
