Yukon HEAT PROBLEM............?
Any GM TECHS out there?
2004 GMC Yukon 5.3
Climate Control,Frt.and rear Air and Heat.
Problem started about a month ago?
The Temp gauge stated showing a eratic Indication?Sometimes would stay on 160 and others would just move all over?I figured the Sending unit was going bad?But,I n the mean time,My wife said the Heat was'nt RITE?The Blower would NOT Blow at all and the Heat was ONLY when you are going down the Road?Basically.its a Gravity FEED!
So,Today?I changed the Temp sending Unit,and the Gauge Still does NOT Work?But,Both Heater hoses are HOT?But the bottom radaitor hose is fairly Cool?So,I changed the T/Stat.BUT,that did NOT change a Thing?
Any IDEAS?
I figure its a Heater Control switch,under the Dash,MAYBE>?
Just Not up on the Late Model S#!T?
Any HELP?Would be GREATLY Appreciated!!!
THANKS!
