The clown who installed my new vaccum and ps pump screwed all kinds of things up. Amoung other problems I need to immediately remedy the following.
1) Exhaust brake won't work
2) A/C fan only works on defrost... most of the time. When I start up in the morning, the system will work fine, that is, the a/c dash vent will work normally. But if I turn off the AC or switch venting, the airflow will immediately go to defrost only where it will remain for the rest fo the day of driving.
Any ideas how to remedy?
