Ac Doesnt' blow hard on max

[dmrodco]

On my 87 vetteIt seems that the AC blower doesn't work any differantly on max as it does on norm. I am sure it is supposed to. it almost feels like the doors are stuck in the by level position. Also does anyone know anything about a upgrade for the blower relay ? Thanks Dewayne

Yes, lots of discussion on this topic since Summer has set in finally for most everyone.

DO a search for AC or Climate Control etc

LOTS of hits I promise

Check under the hood on the blower motor housing .There should be a relay,thats what controls the fan speed.Replace it and see what happens.They are cheap and available at any parts store.

found the problem

Well after checking everything. I found that the little vacuum switch that routes the vacuum to the various doors is leaking. Its the one mounted on the control panel inside the car. Does anyone know if this is available from the dealer or do I need to buy the whole panel ? Thanks Dewayne

This is the unit up above the gas pedal?
multi colored vac lines going in and out of it?

If so, and the unit is not cracked, then simply re-tighten the lines(but not too tight, thats worse than being loose)

Few other guys here on the CAC have gotten under there, pulled the lines, cleaned em out, and re tightened em. All was well after that.
