Good afternoon everybody ! TGIF, from somewhere on the right side below the glove compartment, i'm hearing a sound best described as a a latch or a door to something, having trouble gopening and closing, like it might be sticking in the middle of it's process, a/c is running, is that door controlled by a valve , or the main control mechanism below the radio?What else is down there ?
1997 S10 LS
4.3 V6 Auto A/C

Is there anything wrong beside the sound could just be the ac vent

I blew an upper radiator hose , I think your right, the noise stopped when I shut the a/c off , but it also stopped when I turned off the radio. i just replaced the thermo, and that hose, I didnt hear anything, I was paying more attention to below the motor looking for leaks, i'm going out there in a little bit and start it again , this time I'll run the A/C see if it does that noise.
thanks for the reply,
jeff

sounds like a blend door actuator gone bad.

The truck is not cooling down, while running without the A/C or heater on its @ 210-215, when I shut it off I can hear a high pitch hissing, or whistling. Theres nothing leaking, no steam , just that noise, weep hole from water pump.? I just put a brand new NAPA thermostat in .

Air trapped in the heater core?

after changing thermo you got air trapped in motor , it will run HOT till you get it out

Thank you for replying, and the advice.i'm kind of overwhelmed here, that deal @ Chiltons $30.00 for one tear is that ok , or can I get a better deal elsewhere?, this haynes manual is not sufficient.
