i am pretty sure there are no daytime running lamps on a 90' integra...
Thermostat sticking. Replace thermostat and gasket.
Because it's sitting in the sun.
is the blower motor running? or is it just not blowing hot air?
Your heads are probably warped from overheating. have them checked out by a machine shop. Sometimes they can machine them back to flat, but you might have to replace them.
You mean the outside unit is running and blowing but the inside unit is not blowing? Shut it off! Who ain't blowing? Elaborate please..
compressor not running
did you try blowing it
they dont have day times....
Check the temperature gauge. If it is running cold, replace the thermostat.
Is the compressor running ?
