Whats up guys, first post on here besides the introduction section. So I recently bought a 95 SC400, and one of the problems was that the car wouldn't warm up fully, and the heat was blowing cold.

So I thought it would be the thermostat to fix it all, and I was wrong. The car properly heats up now, but the heat still blows cold. I suspect its the heater core, but hope its not ;/

Any tips, suggestions, or pointing me towards the right thread would be appreciated.

Thanks again,
streetnick

Heat is very sensitive to air in the coolant.

Could be a bad switch

Thank you. After searching the forum (like I should have first, sorry for wasting a post) Thats what I concluded. Im going to try tomorrow and I'll report back if I have any problems.

Streetnick,
I am curious about what you found as your problem -- I am having a similar problem.

Are you sure your heater control valve is functioning correctly? It's on the passenger side firewall, and it should move when you adjust the temp control ****. Mine was leaking and it would get stuck from the coolant residue.

I am not sure but I will check it when I get the car back -- I think I tried to do a by pass of it with a cheaper valve that goes on a ford. I believe there was a forum post about it that I tried to follow but I don't think that worked for me -- I may have to bite the bullet and by an OEM. My car is in the shop getting body work done so I cannot check it. When I get the car back I will check that -- I appreciate the reply. So I take it you either fixed the problem or replaced the valve?

I bought a used one off eBay for around $40-50 and just swapped it in. No need to buy a new one when you should be able to find one used either online or at a junkyard. I think they were the same for the 300s and 400s, but not 100% positive.

Zerodrag,
Thanks I will look on eBay.
