#3384 of 3674 2000 Chevy Blazer Heater Core by bden1

Jul 01, 2009 (6:38 pm)

A shop just changed the lower gasket on my intake manifold and the spider fuel injector on my 2000 cheverlot blazer. Before I took it in the heater worked. The next day when I got it back the heater did not work. The shop checked and said the heater core is clogged. They flushed the cooling system but said the core is bad. Can the work they did somehow contribute to the heater core getting clogged?

2000 Chevy Blazer ABS problems, engages even with normal breaking. pumping the breaks helps. Could this be a bad master cylinder?

It may be a bad speed sensor. It is a relatively cheap fix. It happened to my 2000 Blazer, too. Good luck.

My 2000 Blazer also had bad heater core and I had to replace it. The heater core can be clogged over weeks or months. In my case the symptom was the gurgling sound in the heater core. Then the coolant leaked from the heater core to inside cabin and then to the outside of the vehicle.
 
Looks like your heater core is just clogged and is not leaking. If I were you, I would bring the vehicle to another shop (maybe a reputable dealer or someone you can really trust) and have it examined. They might be able to flush your heater core.
 
Good luck to you.

They may have gotten debris in the cooling system. Quick repair attempt would be to pull the hoses off the core and backflush the core with a garden hose. Note what comes out of the core. If it backflushes to clean water, and forward flushes okay, hook the hoses back up and top off the cooling system with Dexcool or equivilent (long life antifreeze. Don't mix with the 12 month stuff, bad things happen!), assuming that's what was put in after the gasket repair.

Some debris could easily have been knocked loose during the maintenance work. GM's Dexcool will form crud in the cooling system if it isn't flushed and replaced every two years. Also, mixing other antifreeze with the Dexcool will cause the gummy stuff to form.
 
I've never had any luck clearing a clogged cooling system with flushing,. The chemicals just don't eat away the stuff. The only sure cure is to Remove and Replace. Your radiator and heater core may begin to leak due to the corrosion of the aluminum. This is usually due to the electrical current created between the aluminum radiator and iron engine block by the weak antifreeze (same as above).

Two common problems create this. 1) worn/broken ignition switch or 2) the front wheels are turned when the key is turned off, creating tension on the steering wheel lock pin. It can take a lot of effort on the steering wheel to relieve the tension enough to allow the key to move.

#3393 of 3674 Blazer Moonroof Rain Drains by blackrottie

Jul 23, 2009 (6:41 pm)

Does anyone know where the drains are for the moonroof? My 2002 2-door blazer smells of mildew. I think my moonroof drains are clogged but I can't seam to find them so that I can blow them out with a compressor.
 
There are no signs of leaks, I just smell mildew when it rains.
