Re: 99 Suburban Rear Heat blower
You have a stuck relay, not sure where it is, probally in the engine compartment, fan goes thru relay on Hi. Should be a relay for the front fan, could try switching relays to see if prob moves to the front

Re: 99 Suburban Rear Heat blower
On my "old body style" Sub there are 3 relays for the rear blower--low, med & hi. They are located behind the right rear interior panel. And a stuck relay will cause the fan to continue to run as it is powered thru the relay contacts by the "BLOWER" fuse (#3 50a) in the under hood fuse block and is "hot at all times"..............Steve
