i have a 2002 impala, the heater-a/c blower speeds only work on 3-4 speed 1-2 dont. i have found the blower motor under the dash below the glove box but anyone know where the resistors are? i think its a bad resistor but if anyone else has any ideas please let me know.

 

You have to buy a new block resistor. The one you will get is a better version than the older model. It is sealed. I had the same problem with my 03 impala and By replacing this block it work fine now. At the dealer it cost aprx 65$. Be prepare to have a rough time under the dash as it is very crowdy and tight to work in that small area. Get some proper tools like a flex handle for your socket as there is no room for the normal tools. Otherwise with the compact sockets set and flex drive it can be done by a human . Good luck

 

Sorry the location is just above the fan. Pull the carpet and rubber mat out of your way to have a better view. Like I said it can barely be done by human. Also I took the passager seat out of there so I could lay down on my back to have some room. The smaller your body is the better you will enjoy the work.

 

ok thanks for the tip to remove the seat, it sure hurt trying to look under there, i will get the flex handle for sure and i think i found the block on ebay for 45 dollars, i appreciate the help
