PROGRAMMER ADJUSTMENT
1. Open/remove I.P. compartment to gain access to programmer.
2. Start engine and operate until choke is open and off fast idle speed cam. Engine vacuum source or equivalent must be connected to engine vacuum
port of vacuum checking relay during entire adjustment procedure.
3. Set A/C control mode lever to MAX position.
4. Move A/C control temperature lever until left end of programmer vacuum motor link is observed, through open I.P. compartment, to be even with
the left edge of the programmer's cut-out area "A".
5. Hold programmer control lever with hand at "B" to prevent movement during Step 6.
6. Insert a standard flat-bladed screwdriver into the programmer control lever adjusting slot "C" and rotate to move the vacuum motor link as
follows:
a. Rotating the screwdriver counterclockwise will raise the front seat temperature to the A/C control temperature lever reference setting. See Step
(c) below.
b. Rotating the screwdriver clockwise will lower the front seat temperature to the A/C control temperature lever reference setting. See Step (c)
below.
c. A 1/4" movement of the left end ("D") of the motor link (as set up in Step 4) will result in bringing the front seat center area temperature about
three (3) degrees closer to the A/C control temperature lever reference setting.
NOTE: A 1/2" movement results in about six (6) degrees change. (A movement more than 1/2" produces varying change.)
