On a 1996 Pontiac Bonneville SE, the mass air flow (MAF) sensor is located in the air intake duct, between the air filter and the throttle body. It is typically housed in a plastic housing and may be connected with screws or clips. To access it, you may need to remove the air intake hose. Ensure the engine is off and cool before attempting any work on it.
1990 was before GM switched to using Dex-Cool extended life coolant, so any of the traditional green ethylene glycol or universal coolant/antifreezes would work perfectly. Any brand will suit the car well.
Your need to add more r134a Freon. When the levels are not sufficient to cool both sides the car default sends all the cold air to the passenger side and not the driver's side.
The O2 sensors on a 2000 Pontiac Bonneville are typically located in two main areas: one is positioned in the exhaust manifold, before the catalytic converter (upstream O2 sensor), and the other is located after the catalytic converter (downstream O2 sensor). To access them, you may need to raise the vehicle for better visibility and reach, especially for the upstream sensor. Always ensure the engine is cool and take necessary safety precautions when working on the vehicle.

To change the thermostat on a 1994 Pontiac Bonneville, first, ensure the engine is cool and then disconnect the negative battery cable. Drain the coolant from the radiator, remove the upper radiator hose, and unbolt the thermostat housing to access the thermostat. Replace the old thermostat with a new one, ensuring the gasket is in place, then reassemble by reversing the steps. Finally, refill the coolant and check for leaks.
Cool Paradise was created in 1990.
Cool Touch was created in 1990.
Had this problem for the last 3 weeks and finally found that I had a bad ground from the battery to engine. Replace that wire.
water temp sensor wire grounding out could cause this problem.
