The automatic temperature control on my 2000 Yukon works But I would like more control or a different range of temperature. When set at the warmest point it puts out a nice warm supply but then when it thinks its met it's set point it all goes away. Then the only way to get more heat is to move it to the manual hot position. NO lack of heat there, 170 deg. +, I think hamburger is cooked at 160 so I can't take that for long.
Has a temp. sensor gone bad? Can the temperature range be changed?
Thanks for any help, Doug
