6.1) In the following steps we
will be looking at all Surface Mount Resisters, (SMR).
Note - The AC control has bad solder, bad connections at
one, two or more of the main SMR's that will be pointed out in the
following steps. Repair solder on ALL SMR's pointed out. |

7.1) With slight pressure to
side of SMR, this component lifted from the PCB. This shows the solder
connections are bad. You do not need to lift components.
7.2) Repair solder at both ends of 5 SMR's on PCB, top left. |

8.1) First SMR re-soldered.
Solder runs the entire length of the end of the component, both ends.
(Second thru fifth SMR, left to right have not been re-soldered). |

9.1) When re-soldering third
SMR, this component also lifted from the PCB. You may need a small tool to
hold SMR in place while soldering. |

12.1) For good measure,
re-solder all SMR's on PCB on opposite half of AC control, PCB does not
need to be removed from front panel.
12.2) Connect connector to first repaired PCB.
12.3) Install removed PCB back into cover, be careful to align connector
pins through back cover.
12.4) Install four screws and plug into your Corvette to check.
