How To: bypass Heater Control Panel to turn on A/C

[mhopton]

Anyone that's good with electrical know how to jumper wire the A/C switch in the dash control panel to turn the A/C on? The Control panel is bad, which is limiting power to the switch to kick the system on.

Anyone have a spare Heater Control Panel for an 89 LX?

You can jump out that switch. But before you jump it out check that you have 12 volts on the yellow/black wire with the ignition key in the run position.

If there is no voltage check fuse # 5 in the under the dash fuse panel. From your other thread it sounds like the fuse is blown. Turn off the A/C switch before you change the fuse.

If there is 12 volts on the yellow/ black wire then jump that wire to the green wire.

Fuse #5 was the prob.

wish my car was that easy to fix, my blower motor died today the brushes wore out completely and that haines manual did not come close to showing how to drop the fan assembly
practically had to rip it out , now i have to get the motor tomorrow at the auto parts store for 87.00 plus tax, dealer price 276.00

It was a quick fix.. blew that fuse again and further diagnosis revealed a bad clutch/coil.
