Question about 1990 GMC Suburban
I have a 1993 Chevy Suburban 2500 with a heater blower problem. The blower fan started rattling one day and started making a loud noise, sounding a lot like I imagine it would if a small toy or pen or something fell down the vents at the top of the dash, inside. It went on like that for a while then stopped completely, as if only jammed because there is still heat blowing but now the heat doesn't get into the vehicle much and the kids can't travel in it on really cold days. If I had any confidence about being able to take apart the blower and where to take it apart from, and get it back together again, I would. Can anyone tell me where to start?
This happened to me too. I looked under the dash on the passenger side and located the cabin air system intake and it was partially blocked by garbage like cany wrappers and papers. I pulled them out and it's perfect now. Good luck.

Under the hood on the passenger side is where the motor is located.there are 3 or 4 screws that hold it in place and once you remove the fan motor youll know if its bad or not. the bearings may be worn out on it.
