Re: my 1999 buick regal heat is not coming out what...
You mean blower not blowing air? Most times the blower resistor is bad. Run voltage to the blower with ground. If it comes on, replace the resistor. Both are under the passenger side dash.

Remove the air control panel from the dashboard & check the electrical connections. Also look in the fuse boxes for any blown fuses.
However, the problem is likely the airflow control manifold valve. But before you go to the trouble and expense of replacing the manifold valve, check the electrical wiring and fuses as well as any vacuum conections...always start with the simple and cheap possabilities first and word up to complex, difficult, and expensive.ones.
check for power at the plug that attaches to the fan motor. if it has power then replace the fan. if not then trace the wire back to the relay to find the short.
did you check basic all fuses in car and relays if working then jump relay to pump to see if works or unplug connector and test if power and ground are present as well if you think the fuel pump is no good shoot into intake a little gas and try to start if it starts well possible defect pump
If the buttons light up when you turn them on then the fuse is good.What usually happens is the element of the heater part burns or break and the heater will not work.This is a 2 part heater.One for the back and one for the bottom.If one goes neither of them will work.You have to ohm both to see which one is bad and replace it.Usually the bottom because it takes the most abuse.If the light does not come on then check the fuses and check connections under the seat.Good luck.
check for power at all your fuses. good battery with nothing else means there is a loss of power in the circuit somewhere. start with fuses. thanks jeff
