After market ac sucks

[87Scottsdale20]

Hello everyone I bought an 87 Scottsdale with aftermarket ac and I cannot get the flow of the air to come out sufficient. When I took the dash off and looked behind the control module there were 3 nipples and only 2 emission hoses connected to two out three of the ports. I searched everywhere to see if the third hose was just not connected but I had no luck. I put in a new blower motor and I don't understand why the airflow is so week. If anyone has insight on how to fix the issue, please share your experience. Thanks

Do you know who the manufacturer is? If so, they should be able to help. For example, you can download the installation manual for just about any Vintage Air kit.

there's a thread on this somewhere about how it's common that the ducts behind the dashboard have gaps between them that sometimes require duct tape. That is what I did to get decent defrost on my 85 silverado.
