88 300 E Relays
 

Sleepwalker, and anyone else who may be able to offer me some assistance. I own a 1988 300E, and I have been having a few minor problems in the electrical area as well as with the internal heating system. I believe my problem may be with relays. All of my fuses are in good shape, but here is my dilemma. I cannot regulate the internal temperature, basically I have no heat. This vehicle does not have a mono-valve, but it has a secondary waterpump. The waterpuymp is not getting any volts. The next issue is I cannot find the relay for it, where is it located for this vehicle. Is this the same relay that controls the overhead internal temperature sensor? I do not have lights for the seatbelt warning system and the vanity mirrors do not light up. I also lost the overhead light located in the rear roof.
Are these components regulated by the same relay? Is there anyone out there who may be able to post a diagram or tell me the location of this relay?
