HIGH BEAMS WORK LOW BEAM DO NOT

I have a 95 riviera supercharged but the low beams will not work. the seats do not lock back and the motor hesitates under pressure like a misfire. The engine service light comes on how do I read the codes

Thank you

Seats not locking are normal. It's how they operate. Under normal driving conditions it shouldn't be an issue. Under hard braking if nobody is in the seat they may spring forward. It's nothing to worry about though.

Low beams could be caused by a blown fuse/circuit breaker under the rear seat, a bad switch or simply a bad bulb.

Engine hesitating under load could be many things. Is the service soon light on solid or flashing? Easiest and cheapest way to check the codes is to bring it up to autozone and have them do a scan for free. Although the 1995 has OBD1 so it may be as simple as sticking a paperclip in the obd connector and watching the service soon light flash to show codes. Someone else with a 1995 will have to chime in. Anyway, check simple things such as plugged air filter, spark plugs and wires, and just a general look over of the engine before spending a large amount of time or money on replacement parts.
