I have a 2000 Pontiac Grand Prix GT 3.8. How difficult I it to replace the A/C heater blower fan? Recently, the blower does not work on number 1 & 2 speeds. I just changed the switch, but this does not seem to be the problem. I am only guessing at this point that it may be the blower fan. Unless there is a relay switch which I am not aware of.Thank you

Test the resistor block. The blower and resistor block are located under the passenger's side dash below the glove box. Unplug the resistor block snd, using a 12 volt DC test light, make sure you have power on one wire at each of the five blower speeds. If you do, plug it back in and unplug the blower motor. Same test. The test lamp should light up on all 5 blower speeds. If not, resistor block is bad. If so, blower motor is bad. HTH. -Jim

Good morning, Jim and thank you very much for your response. I believe it may be the resistor block as the other speeds work fine. I will try both and see. Thank you, Anthony PS, I had an earlier post about my 2000 Grand Prix GT 3.8, regarding the fuel pump not getting current. Turns out that even though I mentioned to my mechanic of 35 years about this, he said it was not the fuel pump, it definitely was a bad fuel pump. I believe he did not want to tackle this job. I am annoyed about this as it cost me $714.00. The pump was $400.00 dollars alone. I priced my fuel pump and I did not see any above $250.00. Well, lesson learned. Thank you again, Jim.

Good morning Anthony. You're welcome glad to help. I also have a 2000 Grand Prix GT Coupe 3.8L. Very fun car! It's my toy. Very sorry to hear about the fuel pump. At least you got it up & running again. For future reference try rockauto.com. Their prices are very competitive. -Jim
