My heat and a.c does not work. I pushed every button on the dashboard and nothing

What is your question?

Heat and AC does not blow any air what do every out. The controls on the dashboard lights do not come on. I changed the relay and the fuses under the driver side dashboard and 888 showed up on the dashboard where the clock is at and that was all. The clock didn't show up either.

What makes this problem better or worse?

Sometimes the lights flash on and back off where the controls are for the ac and heat but no air or anything blows out

How long has your 1992 Lexus LS400 had this problem?
