i posted a thread a few weeks ago about "check coolant level" that shows up every after engine turn off. i appreciated those who replied. i haven't done anything yet about it and now there is another problem that popped-up - - heater won't work. it just blows air even if its in the 90s. are these two related in some ways? i need replies since it's becoming cold here in texas. thanks again in advance SOS [:X]
