It's a defrost bypass valve that redirects the freon to releave the high head pressure caused by shutdown.When the pressure balances it will go back to normal. An iced up evaporator causes poorheat load levels and it affects the whole system. You may want to have the system chked for a proper charge in the a/c system. Personnaly I wouldn't be concerned. Good Luck, Ned.

My heater/blower fan will not shut off in my 2005 envoy even after my ignition is turned off and key is out, i've read a few similar problems on this, what is the solution and how much will it cos


Depending which HVAC system you have Manual (sliders for temperature) or Auto (digital readout), the control module is likely at fault. The Manual HVAC has a Resistor Module (which have a high failure rate) and the Auto HVAC uses an electronic module. Both of these are mounted next to the blower motor located behind the glovebox.

Why wont my a/c or heater fan come on?


When the blower works only on the high setting its usually a bad blower resistor which is right near the blower motor. now you say it would always blow high regardless of the fan speed setting that would indicate probably the climate control unit or a connector problem somewhere. finally it not working at all may be the climate control unit or connection went bad even further. it might have a blown fuse or a bad blower motor in addition to the climate control unit or connector problem .check for power and ground at the blower motor. the power is supplied from fuses and may have a relay also. the ground is supplied from the climate control unit and goes through the resistor to control the fan speed. good luck

2003 chevy avalance a/c blower moter runs with ignition shut off


If you have the automatic climate control and the blower motor won't shut off then you have a failing Blower motor speed control module. Something inside this module goes bad and the result is a blower motor that keeps running at times even though the engine is off and the key is out of the ignition. The module isn't repairable but has to be replaced. I believe it is located behind the passenger side of the dash panel.

My heater puts out heat however the blower motor does no run


I am going to assume that you have the Automatic climate control on your car. it gives you an auto fan mode, and temperature options. Often the problem does not lie in the blower motor, but rather, the climate control module. Often, the blower motor only works on Auto fan mode, or on full out. It will often also only operate in certain modes, such as only in defrost mode, or panel. I have had several town cars and Grand Marquies of these era's and have had the same problems with 2 of these cars. The only good solution to the issue is to replace the climate control module, which is the panel with all of the switches for the heater controls. If you're really adventurous or cannot find the replacement part, it may be possible to hard wire the fan to a multi resistance switch, but you really got to know what you're doing.
