Question
.....
sorry if i sent 2 replies

im not sure what all they had to remove but im fairly sure they needed to get to the back of the radio. i dont think they removed any of the rest of the dashboard.

all that is correct. there is no air flow at all, from heater or defroster, and i cannot hear the blower running

Question -
i have a 1999 sts and recently the ac/heater blower stopped working. the rear fan blows air but there is none coming through the vents in the front. i have checked both fuses and they are both alright. i just recently got new speakers installed in the back and they had to remove the panel to hook up to the rear of the deck. the blower didnt stop working until a week after the install but im thinking maybe that still had something to do with it. any suggestions?

Answer -
Did they remove ANY panels on the dash where your A/C vents are located or worked in the front dash or under the front dash ?.

You have NO front blower fan operation at ALL ?. Correct ?.

No air from defroster or heater vents ?.

you can't even hear the front blower operating ?.

Answer
