It could be a loose ground behind the dash or even a likely bad dimmer( the one you use to control the brightness of the dash lights) or head light switch. i personally have had the same issue with a nissan and it was the dash light dimmer switch. hope this helps

Which dash lights blink, do they blink with engine running or just ignition on. First thing to check are battery condition, is it able to supply required volts and current if not sure have it tested by your local auto shop. Make sure all connections at battery posts are clen and TIGHT, I emphasize tight many people overlook this simple thing and begin chasing their tails. Hope this helps you.

SOURCE: friend jumped 97 lexus 400 now power seat,

Check fuses for whatever doesn't work. Fuse box location and diagram should be in you owners manual. Make certain to note amps of EACH fuse and don't mix them up. The fuse that goes in MUST agree in amps with what fuse came out for each slot. Amps for each fuse should be stamped on fuse box next to each slot.

Dash light blink on and off


Sounds like you have a bad power rail or ground connection point under the dash.

You best bet is to get a factory service manual (local library usually has one, not Hanes or Chiltons, or Motors).

Dash lights


To my knowledge only a lexus dealership can correct the air bag light, also it seems that with the older lexus models that dash lighting is a common issue. I would suggest checking your fuses for loose or burnt out ones, as well as checking for loose wiring in the dash unit itself which a mechanic should be able to diagnose. not sure if that helps at all.
