Product Details

This 28 page PDF manual with 55 photographs will take you step by step through the process of quickly finding and repairing those leaks. Starting at the firewall and working all the way to the trunk/deck of your car, I will show you how to isolate the problems even without having to take the door panels off.

To aid in trouble shooting you will need to acquire an inexpensive vacuum hand pump. Normal hand tools are the only other things you will need. For 1977 to 1980 cars I even have vacuum actuator repair kits available so you can replace any cracked diaphragms you may find.

PLEASE NOTE: as an added bonus I have included all the information contained in my 123 Door Maintenance Guide in the appendix of this manual (no need for you to purchase that separately). This will show you how to properly remove your door panels and do other related maintenance inside your doors while you are working on the vacuum door locks. There are even instructions on how to properly deactivate the automatic door locks if you should so choose.
