1995 Park Avenue heater A/C tempature reading flashes

When I start & begin to begin driveing the temp light on my heater flashes for 2 or 3 minutes. The heater system works OK (the weather is to cold to check the AC) I'd like to fix this as I'm afraid it my become a bigger problem later.

Ii had the same problem, fixed it temporarily by detaching the battery for a moment, this reset the blinking temp display. Nevertheless, the solution to the problem was filling the air condition up with coolant.

One or more of your actuators is malfuntioning.  they ar eunder the dash.  I had a mechanic repair mine for about 400 bucks.  the dash needs to b removed and some very tight spots to work in.  the flashing is maybe caused from the sensor.  either outside air tempo sensor or inside. does it blink while showing the inside or ouside.  not exactly sure where the inside is, but the outside is in the center in front of radiator when u open the hood. black about the size of a tube of chap stick.

    Security light on and flashing, reads key code...


    Looks like the TDM in the security system (VATS/PassKey) is having problems, it's typical on those cars and it can get worse till the car wont start anymore. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.

    No air conditioning, flashing climate light


    You should make sure you have proper charge for sure.has your battery gone dead lately? I know on some of them digital climate controls will act exactly like this and have to be reset or go through a setup sequence.

    PA blows cold air everytime I restart the car


    The cooling thermostat may be failing since this customarily diverts hot water to the heater core first to give a faster response. That isn't an expensive or difficult job to replace it so I would start there. If the system is going to be opened anyhow, I suggest you flush the system first. That may even solve the problem.
    Coolant will be lost in the replacement so catch as much as you can to avoid having someone's pet lap up the stuff and die.

    1995 Buick Park Ave. Brake light remains ON and chimes on driving


    The problem is the car think the park brake is on (intermittently). I would check the park brake switch, perhaps it's loose, or perhaps the park brake is pushed down to the first "click" spot. Also check the wiring connection to the switch, and the wiring nearby. Good luck!
