Lights stay on. on 1994 Honda Passport

the fuel,battery,and brake light stays on and the air or heater stopped working what could cause that problem

Usually the heat goes out because the heater core goes bad.

that would be alright... but there shouldnt be anyreason for that. it worked then other day, and we havnt used it since the car has been out of service.... and as for my lights. my brake light has been on for a long time, but the gas and engine light came on the other day when we put the new alternator in...
mine is doing same thing the heat issue on mine is the blower wont come on all started at same time all was great before
