you might have battery tested, all cable connections checked to make sure they are clean and tight. maybe change the serpentine belt as well.

the tahoe suburban and silverados are pertty notoriouse for blower motors and resistors going out. ive never heard of the lights dimming. do this. under the dash on the passenger side there is a black cover. should be screwed in with three or four screws. take that cover off and the blower motor and resistor is on the right hand side. disconnect the resistor connector. the big one. i believe its a seven wire conn. make sure its not melted. if it is, replace the connector and resistor. if you need further help you can call me. 214-472-6803
