so suddenly while owning 2009 h3 with auto transmission i5 engine

the temperature control is useless

turning it counterclockwise to the end will get me cold air

just one click clockwise will get me "HOT" Air

before it was fine

tried to enable and disable recycle (no help)

tried to do it with comoressor kicked in or out (same results)

the problem is which is i am thankful that the ac is freezing cold
i wish if i can increase the temperature a bit to my liking but no joy

thanks ;(

edit; got the upper radiator plastic peice replaced it was leaking however it didn't overheat

i don't remember if the problem was before or after the leak but i am 95÷ sure it was there before the leak

 

theres a calibration for the temp . search? worth a try.

 

i never knew that there is precedure about this untill now,

unfortuntly it didn't work one click clockwise give full heat and one click counter clockwisr gives ice cold
breeze

whsts wrong?

 

Please use the search function, there are many threads about this, a lot link back to this one. https://www.hummerforums.com/forum/h...me-help-28289/

 

Is it normal for the temp gauge of an H3 to register between half and three-fourths to the hot range?

 

Yes..

 

really appreciate your help,
my searching skills wouldn't get to that link apparently( i admit i didn't think of searching thought my case is isolated incident and never thought of diy fix, thought the whole thing needs replacement)

you got the right term "climate control" i would have used temp control or other terms


the full diy is posted in page 4 by Hunner


i may start doing it soon, just lots of trouble getting ac power to the garage to run the solder iron


thanks Doc Olds

 

you could do a tight twist on the wires or two small wire nuts. theres no current involved

 

can you explain further please ?

 

you indicated a problem getting soldering stuff in place. my suggestion is to just add the resistor by twisting or wire nutting instead of soldering.

im assuming you are trying the mod/fix using a resistor.
