Replying to: gonogo (Mar 23, 2008 2:11 pm) I have the entire Dash apart, and I'm not able to find any "actual" Grounds, anyone have an Idea to where the Grounds inside are located? Replies to this message: gonogo (Mar 25, 2008 7:57 am) sn4ck0 (Mar 25, 2008 10:27 am)

Replying to: sn4ck0 (Mar 24, 2008 12:56 pm) The plug with all the wires, one or more is ground. Now you need to find out where they are grounded, close by I would say. Replies to this message: sn4ck0 (Mar 25, 2008 10:27 am)

#41 of 57 2000 Chevy S-10 Blower Motor by boomerff373 Mar 26, 2008 (5:36 pm)
I just noticed that my blower motor only seems to work on 3 and 4 now. I was just wondering if it is a bad blower motor or if the blower motor resistor is bad? Any help would be appreciated.

Replying to: boomerff373 (Mar 26, 2008 5:36 pm) I have heard the Same issues, with the HVAC Switch only working on "high" and the problem being the Blower Motor Resistor.     If your Blower Motor is working, I think you could rule that out, The BMR, is roughly 17$ of course depending on where you're at.     As I've just replaced my BMR, trying to resolve another issue, I know it's a simple task to to replace.

Replying to: sn4ck0 (Mar 26, 2008 5:55 pm) Ah okay, I was kind of leaning twards the resistor. I looked it up the other day, about 22 bucks at Advance Auto. Thanks for the tip.
#44 of 57 warm air? by 03gmc Apr 22, 2008 (2:54 pm)
I have a 03 sonoma w/ manual climate controls. I have noticed that some one else posted a question about my same issue. With the temp selected to cold and the air flow off I get warm air through my heater, also if I select defog, heater, or blend I still get warm air which is very annoying when it's 60 degrees or warmer outside. Is this normal? All the other GM vehicles I've owned would actually blow COLD air if defog was selected. My A/C works fine. And I can hear my A/C pump engage when selscting defog. I checked my mixing actuator coming off the heater core and it seems to be getting full movement in both directions. Any suggestions?

Replying to: 03gmc (Apr 22, 2008 2:54 pm) Sounds like the temp actuator is not moving the valve. Is the large line going to the compressor cold on A/C? Replies to this message: 03gmc (Apr 23, 2008 11:17 am) gonogo (Apr 24, 2008 9:00 am)

Replying to: gonogo (Apr 23, 2008 9:07 am) Yeah, The a/c works fine. I was able to observe the temp actuator and it seems to getting full movement in both directions. There are actually reference marks on the duct that coincide with the actuator. They seem to line up also. The only thing I can figure is the temp actuator doesn't quite close the whole way.

Replying to: 03gmc (Apr 23, 2008 11:17 am) well with my 99 I have to have dash vent on, or I get heat out the floor vents. Dealer said normal, they all do it. The A/C is so cold, I have to modulate with heat or I would freeze, even when 90+ out.
