Over the past few days I have had no heat in my Blazer. I did have heat about 3 weeks ago. Now there is no heat at all. The AC works fine. Last time I had my oil changed about a month ago the guy told me my radiator should be flushed soon. Think maybe its a simple issue like a radiator flush or could there be a core issue?

Looking for any help or advice.

Thanks!
Mike

Take it in and get them to do a full reverse flush and replace the Dexcool with fresh stuff.

Your heat will come back.

Also, is the Blazer warming up to the half mark on the gauge?

Yes the engine is warming up the gauge shows to the half mark after running for awhile.

Thanks so much for the advice!

My blazer never warms up to the 210 mark, its always just above the mark below it, do you think theres something wrong with my cooling system if it isn't warming up all the way or is it just a gauge?

Nope, you are completely fine.

195f is the stock thermostat.

Now if it didn't get above 1/4, then worry.
