I noticed that if its very cold out, the heat dissipates thanks to the strakes and engine vents. So, in town driving I get more heat until I open it up on the highway.
Try closing the heat outlets in the footwell (push button down, no lights on the indicator). Also, my rotary fan switch is sometimes rubbed by my cellphone cord and turns down or off.
Taz may be able to chime in with ideas.
BTW, mine is an 88.5 TR and not a 512.
