I have ripped my car apart to fix a no-defrost problem. This includes taking the inner (& outer) fender off and replacing the blower motor. Now it will not blow air up to the defrost. So I took the heater/AC box out and found that the twin diverter doors were in need of some freeing up and did that. Wanted to make sure that all vacuum was working before putting box back in. But there are a lot of them and the vacuum coming from the canister on the firewall is weak. Does someone have the appropriate vacuum diagram they can send me? Or can someone verify which manual this diagram is in (obviously would prefer an image)? Or just some general wisdom born of experience? Thanks.
