is it true that u can just take off the plastic cover on the knobs to achieve the clear knob look.. i have seen people that do this and i was just wondering

sure is...

pull the knobs directly off the HVAC unit... start at the edges and work you way in.. it does require a little bit of time.

and in some cases force lol..

hah, i cut mine with a exacto blade.. then glued back on the lil green things

Use a blow dryer, then peel em off.

I havent done it though, looks tacky IMO

I think it depends like if that is all you have done to the interior then yes Tacky... but like my interior is all white and red. they look ok.

I painted mine red and it looks good
