Front heater will blow cold air most of the time--sometimes will get "luke warm". Engine has never over-heated, or ran hot - but temp gauge has started to fluctuate from half way to a little over halfway. Replaced thermostat and situation has not gotten any better. No anti-freeze leaks or overflowing, not anti-freeze leakage into oil either. SOMEBODY PLEASE HELP ME?

Are both the heater hoses going to the heater core at the firewall getting too hot to hold?

Unfortunately I have NO IDEA where those are located. I understand where the firewall is. But are they located inside on passenger side? Also, do I have to rip anything apart to get to them to feel them? Other people have been saying to check them, but I don't know where they are at specifically to be able to check. Would that cause a fluctuation with my temperature gauge? I feel so lost. :(

There inside your engine compartment about half way down the fire wall.I am thinking a restricted or clogged heater core thats why I asked you to check themIam not sure how accessible they are moving things etc. But that's are starting point.
