1997 lexus ls 400 the heat and air is not working.

The air just cut off one day. Out of seven years I have never put any water or cooliant in it. The LCD screen lights up but no air blows out. The black words do not show also what could this problem be. I have changed the LCD screen twice nothing happened. Could you please help me. It is cold as hell in that car. Thanks I need it. ASAp would b good. If I need cooliant can I use 50/50 without adding water. Or do I have to go to garage.

Yes you can use 50/50 coolant and do not need to add water also you have to put in enough coolant in the car and to make sure the car runs until it gets to temp to make sure you have all the bubbles out of the system

Lexus won't stay running

The crazy part about it my car doin the same thing.Part of problem was I had got some bad gas from a cheap gas station( so watch your gas) I replaced fuel filter and pump (by car shop) and put in jet cleaner also. When I took car out shop it was still doin the same thing. I have changed the throttle position sensor and it seemed like it half-way fixed the problem, but now all it do is stall or cut off when touch gas pedal.
