no heat 1998 blazer

my 1998 blazer only blows luke warm heat

first check antifreeze...
then replace thermostat...
if its still not blower hot its prob the heater core...

my heater core just went too... does the window get foggy inside???
is the passenger floorboard wet with antifreeze???
if so its the heater core... but the antifreeze and thermo are cheaper and easier fixes... check em out!

we replaced the thermostat there is no antifreeze on the floor and windshield the dont fog up.

Automatic or manual heater controls?
Is the engine reaching normal tempt?

does it change with the your heat control? (i.e. - is it ALWAYS luke warm, or can you get it to change to cold as well?)
