#3380 of 3449 AC Clutch needs replacing by pkirwin Jun 28, 2009 (8:44 am)
My 04 Blazer with the big V-6 has an AC Clutch that is stalling and squeeling. I thought that the problem just might be low freon, but I can find no leaks and the systems is still putting out ice cubes. I need to know what kind of tools and the proceedure for doing this myself. I have worked with AC before, own two classic cars, and have a wife with an extensive first aid kit. While I am there, I plan to replace the water pump and the big rubber band.

#3382 of 3449 Help by 95jimmy Jun 29, 2009 (8:17 pm)
I have a 95 2door jimmy. It has about 194k on it. For the most part it runs great but when it shifts from second to third the truck jerks forward a little bit. Is this a big deal or no? Replies to this message: Mr_Shiftright (Jul 01, 2009 7:18 am)

Replying to: 95jimmy (Jun 29, 2009 8:17 pm) Well hard to say. As a car ages the seals in the trans get old and less flexible, and the valve body might be sticking---and then there's the usual wear and tear on clutch packs, etc. If you are really concerned, you could drop the pan and check for excessive amounts of metallic debris. That would be a warning sign. Also some nice clean fluid and a filter, and perhaps a good conditioner, might help you along.
#3384 of 3449 2000 Chevy Blazer Heater Core by bden1 Jul 01, 2009 (5:38 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? Replies to this message: auto9999 (Jul 01, 2009 9:39 pm) jlflemmons (Jul 04, 2009 2:05 pm) johnss10 (Jul 06, 2009 8:26 am)

2000 Chevy Blazer ABS problems, engages even with normal breaking. pumping the breaks helps. Could this be a bad master cylinder? Replies to this message: auto9999 (Jul 01, 2009 9:31 pm)

Replying to: bden1 (Jul 01, 2009 7:02 pm) It may be a bad speed sensor. It is a relatively cheap fix. It happened to my 2000 Blazer, too. Good luck.

Replying to: bden1 (Jul 01, 2009 5:38 pm) 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.
