I have a 92 oldsmobile 98 regency. The past few weeks my headlights only work intermittently. On my dash it says that my lights are on and when I turn the switch it dings as if they are on but only my parking lights work constantly. Any ideas as to why this could be happening?

you may have to turn to your DMM and a wiring diagrams to isolate this problem.
Intermittent operation of headlights can be cause by an connection issues with switches, fire wall bulkhead connectors, in-line connectors, head lamp connector, fuse,or relay blocks.
check also for weak circuiy breakers
problems with head lamp relays, short causing circuit breaker shutdown, bulb problems, faulty relay.

Suggested Repair

Use a digital multimeter and wiring diagrams to isolate the intermittent headlight circuit. Inspect the headlight switch, firewall bulkhead and in-line connectors, headlamp connectors, fuses, relay blocks, circuit breakers, and headlamp relays, and check for weak breakers, bad bulbs, a faulty relay, or a short that trips the breaker.

Conversation Summary

The owner of a 1992 Oldsmobile 98 says the headlights work only intermittently. The dash shows the lights are on and the switch chimes, but only the parking lights stay on consistently. The expert recommends tracing the circuit with a meter and diagrams and checking connections, relays, circuit breakers, fuses, and bulbs, including a possible short that shuts the breaker down.
