'89 Honda Accord LXi 3DR MT

About three years ago, pressing the AC switch caused a short which blew
out the heater control unit. Easily fixed by replacing the 10 amp fuse.
I decided to let the matter rest and ride without AC.

Today I noticed, that pressing the AC switch no longer causes a short,
but the compressor will not come on when it would previously when the
short occurred.

I recently had the combo-switch (hazzard, turn signals, wiper) go out
and was replaced by the a Honda dealer. In replacing this switch, they
had an issue with 'some other wire' which was preventing the
combo-switch from working properly.

I have no electrical diagram to see if these issues are related, but I
was wondering if they could be. I have not checked the harness to the
compressor as of yet.

The car only has 141,000 original miles and I'm willing to get the AC
fixed if it won't cost an arm and a leg. But I'm probably better off at
this point with an new Accord 4 banger

Any comments appreciated.
