heater controls blinking

[chevy_ss_383]

my heater controls will sometimes blink when its cold out and the truck hasnt been running for very long. all the arrows on the left blink, and it wont let me adjust anything. sometimes turning it off will take care of it. other times, turning it off wont do anything, and sometimes it wont let me trun it off at all. is the module going out?

mine does that once in awhile too, especially when i turn the headlights on, looks crazy everything flashing and stuff like a strobe light, looks kinda cool sometimes
everything still works tho just cant tell where the heat is set or anything, has been ok for the last couple weeks tho so im thinkin its just something loose

Mine was doing that sperratic disco light thing too…

I ended up buying a GM rebuilt one off ebay for under $100 ~ works great!!
