To add Freon to a 1998 Oldsmobile Bravada, first ensure you have the correct type of refrigerant, typically R-134a for that model. Locate the low-pressure service port, usually found on the larger diameter AC line. Attach the refrigerant canister with a gauge and follow the instructions to add the refrigerant until the system reaches the proper pressure. Always check for leaks and ensure the AC system is functioning properly after refilling.
If your lights are flickering on your 98 Bravada, you might have a shortage. It can also indicate that your alternator is failing.

A factory GM system which uses R134a Freon...........
ding freon will make it colder, only if freon is low. if freon is low you have a freon leak so adding will be wasting time and money. more likely to need a new ac temp thermostat, which is no big deal to change
