When I engage the heater only cold air blows out. What should I do to trouble shoot and fix. Thank you.

You've got two hoses going into the firewall on the passenger side of the engine compartment. Feel them when the engine is up to temperature and see if they are hot, if one isn't you've got a plugged heater core. That could cause the no heat. Let me know how it goes and we'll go from there.
