All buttons seem fine but when the heater is on it blowa out air not hot at all but its not completly cold either. can sometime be plugged up or a valve inside.

8) On 60 it's a manual door. Make sure the cable is moving correctly. Maybe the heater core is stopped up or air locked. Also if the thermostat is stuck open could cause it to not heat up enough. Also low coolant level .

Thanks,
I replaced the thermostat but it turns out to be that the manual cable was indeed faulty. The cable wasn't opening the door properly now i got excellent hot air. thanks
