Toyota Repair: Heater, climate control system, indicator bulbs


Question
I have a 91 camry LE with pushbutton controls.  When I move the level from cold to hot it just blow warm air.  I have already had the thermosat replaced,  Can you please help me out.  Also I am having a problem with my display by my steering wheel which tells you what gear you are in.  It lights up in park, reverse, but not in drive and second gear

Answer
This is an auto climate control system and is somewhat complicated, the most common cause for problems is the in dash control unit or the servomotor, I would advise having a toyota dealer check it. Another problem may be that the heater core is partially clogged.
The indicator bulbs are replaceable, the instrument cluster will need to be removed from the dash and the burned out bulb replaced.
