I Have A 98 Blazer 4 Door. I Don't Get Any Heat.my Blower Is Working And My Tempt. Does Not Go Over 110-115.any Sugg. Would Be Appreciated. Thanks.

welcome to af.
if your engine temp is not getting over 115 then you may have a thermostat thats stuck open and that could be why you don't have any heat. is your fuel economy low or does the truck feel sluggish at all?

Exactly what ZL1 said.... I would have the thermostat changed and flush the cooling system and replace with dexcool only. Good luck and let us know the outcome

Yes. It should be up to operating temp after 10 miles. By bet is a stuck T-Stat.

Depends on the outside temperature. Is the weather cold where you live/work?
