2002 park avenue, dash display malfunction, the problem started out as though the displays wanted to go to night brightness during daylight hours, I would hear a click behind the drivers side of the dash much like a relay, at the same time the brightness would change. After a period of time the same problem would happen but the displays would turn off and later back on with the relay sounding click. As time went on display would stay off longer untill eventually the display does not light at all, after this happened the gas guage now jumps back and forth when the fuel is under a half a tank. This all happend during summer time weather, dont know if this is a contributing factor but temp might.
SOURCE: Buick park avenue 1994 heater not working temp.display blinking
off the top of my head you probably have digital controls
the jump probably gave the heater relay a jolt of elec. which made it freeze open or shut
try disconnecting battery for 5 minutes and reconnect it this should reset relay
also heres something to look at even though it gets cold a hose could have split and slow leak on passenger side check floor for wetness if so take to nearest auto shop this needs fixed right away
i had a car that the relays froze shut so i had to manual start it under neith the car with a long screw driver cause key wouldnt start it
temp guage only shows temp not low coolant you gotta pop the hood and check manually the coolant tank for low fluid
even with low fluid the car would have heated up quicker so the idea of low fluid is a gasp heater would have heated quicker too
check condensor in front the small radiator infront of big radiator to see if iced up a little hose water sprayed on it should loosen the ice if any try to see if theres a way in mornings to see if you have any coolant leaks
coolant leaks can break a car into parts and be costly

Same here. What I do is lock all doors using the button on the driver's door before opening the door, then open the driver's door and lock it manually. That seems to keep it disarmed. I believe it has to be the driver's door for this to work, but I don't know for sure.
SOURCE: 94 Buick Park Avenue that stutters under a light load
my 94 park avenue would stutter around a specific rmp range, and usually under a light load. this was caused by the plug wires being bad, they didn't look bad, but once replaced, ran perfectly.
start the car, and rev the engine (don't be afraid to rev through the full rmp range), checking to see if the stutter happens at any specific rmp range (mine happend around 3k rmp). if it does, this is a sure sign that your plug wires are bad & need changed. if they've never been changed on your 94, good idea to change them any how.
sounds like it may be the wires, if your plugs helped some, the slightly better spark would help, but the wires could still not be transporting the current efficiently enough, causing the stutter.
hope this helps.
SOURCE: fuel gauge changes the amount
The fuel sender is in the tank and is part of the fuel pump module ( all in one). the fuel sender is a rheostat and is like a dimmer switch in you home to dim lights, the higher the level of fuel the more voltage the computer sees hence the lower the fuel the lower the voltage it sees. With the age of the car this is likely the problem. But there is a part in the instrument cluster that reads this voltage and sends power to the gauge intermittently. In older cars it was called a anti slosh module. It was there because as the car went up and down a bumpy road the gauge would read erratically. the cost can be prohibitive to fix this but if you can live with it i would. If not expect to spend 600 dollars or more to trace it down and fix it.

The IPC detects a loss of class 2 communications with the PCM.
Fuel Gage
When the fuel level is less than 14% (84ohms), the low fuel indicator illuminates.
Speedometer
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:
?€¢
The PCM detects a malfunction in the fuel level sensor circuit.
?€¢
The IPC detects a loss of class 2 communications with the PCM.
Odometer
The IPC contains a season odometer and a trip odometer. Momentarily press the trip select/reset switch in order to toggle between the season odometer and the trip odometer. Press the trip select/reset switch for greater than 1.5 seconds, while the trip odometer is displayed, in order to reset the trip odometer. The IPC displays the vehicle mileage and trip mileage as determined by the IPC. The IPC calculates the mileage based on the vehicle speed information from the PCM. The odometer will display 'error' if an internal IPC memory failure is detected.
PRNDL Display
The IPC displays the selected gear position as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the gear position. The PRNDL display shall flash all gear positions if:
?€¢
The PCM detects a malfunction in the transmission range switch circuit.
?€¢
The IPC detects a loss of class 2 communications with the PCM.
The IPC displays the vehicle speed based on the information from the PCM. The PCM converts the data from the vehicle speed sensor to a 4000 pulses per mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 mph (0 kph) if a malfunction in the vehicle speed sensor circuit exists.
Tachometer
The IPC displays the engine speed as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine speed. The tachometer will default to 0 rpm if:
?€¢
The PCM detects a malfunction in the engine speed sensor circuit.
?€¢
The IPC detects a loss of class 2 communications with the PCM.
