Loud 'blowing' sound when driving in first gear...
When I first start my blazer and take off in first gear there is usually a loud blowing sound that gets quieter when the trans shifts into second gear.
This only lasts for about the first minute of driving the vehicle and then everything runs quiet.
Any idea what this could be?

Normal fan clutch operation, Winter or Summer. The severe duty clutch takes longer to disengage when cold and engages at a lower temp when the radiator starts to overheat. If it stays engaged, it's broke. If it won't engage, it's broke. The standard duty clutch will shut up quicker on start ups BUT, it will allow radiator temp to increase higher before it engages. Don't like the noise? Get an electric fan, but be aware, they're quieter because they don't move as much air to cool the radiator. Think of the fan as a thermostat for the radiator, not the engine, it has its own thermostat.
