It's my girlfriend's 98 blazer. No heat not a big deal, but it rained and fogged up the windows and she almost crashed last night so probably a good thing to fix.

It blows air, just not hot

Can you please let me know things I can test easily myself before I shell out money to a mechanic? If none work, what the common reasons for this and the typical costs to fix?

Thank you!!

Unhook the coolant hoses going to and coming from the heater core and try to flush water through them in both directions. If it blows air but it doesn't get hot then a clogged heater core is most likely.

Damn bro, letting locked FG sellers into D2 East now?

you would post something d2 related/completely irrelevant to motorsports. stay a nerd 4ever lil puppy.

fats stay mad so long

eah.....


sounds like the notorious heater core to me.....

is the passenger floorboard/carpet damp?


and boy are they fun to replace, id like to think im a fairly good knuckle buster, and it took me 5ish hours to change my brothers on his 2000 blazer, you have to pull the dash, its awesome

repair shops charge like 800-1300 to repair a 30$ part.

sucky.... wish there was just a way to change it like on my bronco where you just pull the glove box out

i actually weigh 160 now. still havent had to lift a weight. keep playing your 10+ year old video games.

Talking about D2 on a D2 forum, no need to be upset about it tubs

i will be willing to bet its the heater core just had the heater core go out in the service truck not to long ago.

Um...is there coolant in the car?
