Hey people never really used the heat till about now since thermals and giant bubble jackets dont cut it no more. I have a 1JZ no A/C it was completely removed thats about it. I get nothing but cold air and the manuals are just confusing me and its cold outside. If I drive for a while hit the heat i'll get a quick burst of heat then just cold air, is there a valve I can just plug up? Any info or anything would help because they think theres something valuable under the comforter and I don't feel like cleaning up glass
