RE: 1987 300 SDL A/C & RPM problem?? please help

Here is the update, I have founf out that my car is missing 2 relays, the OVP and Refregrant compressor and cut off relays. Its supposed to go infront of the drivers side between 2 firewalls. I went to a local salvage yard, picked up both the relays.

I am having an intermittant affect, ie I am having the problem of ABS light ON, RPM (tacho) not working. But after putting the OVP, the engine revvs differently suddenly when I go onto a pot whole or a bump, sometimes not all the times, and this causes the ABS light to vanish and Tacho to work! But still the A/C blows hot air. I am really really getting confused now.

I would really really appreciate some help.

Thanks
Mehdi
