99 grand prix gtp. Annoying problem no heat!..Cold!!

hey wats up AF im having an issue with my car that needs to be taken care of due to the cold ill try to explain best that i can! my car has some type of short or issue with the wiring for my heat and my hvac info display right above the heater (i have the one thats all digital, gtp supercharged model) and my ac/heater control (dual control digital). everything used to work all right with the exception of the hvac info being a little dim

1. my ac control started just flickering on and off, working from time to time but 95 % of the time it doesnt work. i bought a new ac control in case that was the problem but same thing.

2. when i unplug the heater control the hvac info isnt dim anymore and its accurate like it should be..

3. now when i turn the heated seat switch on the hvac info dims all the way off and flickers off and on like the ac control lights do...

4. when the heated seats are on i hear little popping noises but the seat heats fine (the only heat i have)

5. the heater control will not turn on right no matter wat is pressed, but everything works stand-alone..

6. where im at theres no shops that wanna do any electrical auto work and i know i could figure something out with a little help n advice...

any advice is appreciated...

(P.S.) Every fuse works i used a test light to check eve the ones under the hood

Hey AF just posting to let u kno i figured out the problem, it was the ignition switch/harness so for anyone with a problem like mine with the AC/DIC/DRL check that, its probably the last thing anyone would even think about!

(BTW sorry when i said the HVAC info display i meant the DIC!)
