Can someone please help me with my 2003 Acura tl type s, nothing is coming out of the vents when i turn on the heat or ac. Can someone tell what could cause this.

 

Theres no air at all? Have you tried moving the fan speed manually instead of auto?

 

Blower motor is inoperative. Nothing will go on . Check the white connector that feeds the motor.. Motor is under the glove box. Good chance it is corroded or melted. May need a motor (about $50-100on line) and a connector. The connector is part 04321-SOK-A00.. This issue is well known

 

im not sure but it might not be ur blower motor.
i have the same issue but mine have NAV. im not sure whats its called but its somewhere under your glovebox its a transistor or something replace that and it should work. the pix on this link https://acurazine.com/forums/2g-tl-performance-parts-modifications-116/c-blower-doesnt-work-730675/

 

the blower motor power connection is right below the glovebox, you can see it
may have to unplug to inspect for loose wire or crud buildup- burnt wire look
Acura makes an update kit for 8 dollars with new connectors and longer wires- to relieve strain on connection, part number is listed in post above this ,,,easy diy

at the same time you want to replace the cabin air filters, remove glovebox- simple
then the blower motor is staring at you- on its mounting plate is a resistor- not transistor, inside a heat shroud
remove its cover and inspect for burn marks

see cabin filter diy for tips like using shop vac to clean leaves etc, lube the valve for heater and more

do use a cushion on ground/kneepads==concrete is hard when kneeling for 30 minutes doing the job
Note dealer gets over 1.5 hours for just the filter change! save big on this fix and service
note2 should replace cabin filters every year, under 20 bucks for the pair, comes in a 2 pack -as we require

 

note3 use of cabin fan on high/5 all the time,, seems to worsen the problem.
more electricity = more heat in the wire
