I have a 2005 Chevy Tahoe Z71. The heat is very weak even when on full blast. When the engine is reving I get a little more heat but nothing close to what it should be though occasionally it will get hot. I am hoping that we dont have to replace the heater core. What are some cheaper alternatives to try before ripping my dash off to replace the core?? Thanks in advance:)

you might have the alternator checked or simply replace it.. i would also replace the battery if its more than 2 years old

This is a specialist job These things are very dangerous if you don't know what you are doing! Sounds like it has a fault Don't try playing with it !!!!!

as long as all the fuses are good.. its probably the blower resistor/module... located next to the blower motor under the pass. side of the dash..

you are probably correct. there are two contacts on the level sensor that wear out, which gives you the fluctuating gauge.
