Does anyone else who has put a SPAL blower on the back of the Frigiking underdash unit have a problem with too little air flow out of the louvres? Even the louvres directly in front of the blower. My SPAL blower is mounted nicely on the back of my underdash unit, and the air outlet openings on the blower line up fairly well with the openings on the back of the evaporator case. Air flow before the evap is great, but once the air passes thru the evap, the flow is much less, pretty meager. The evap has been well-cleaned and all the fins have been straightened out. Years ago, when my Frigiking was working with the original blower, I remember having much more air out of the louvres (and more blower noise too).
