87 blower relay
If you are talking about the A/C-Heater blower motor relay, it should be under hood near the blower motor itself. At least that is where mine is on my 87. It should have a silver metal cover, unlike most of the other relays which are black plastic.[IMG]

Do you have standard or the C68 electronic controler ?
As pictured above I have the standard controler but mine has a black cover but same location, there is also a blower resistor just above that to the right in the top of heater box. This is assuming you have a standard controler.
If you have the C68 you need to find the A/C underhood fuse & amp which provides power to the blower feedback signal input. There is also a Blower Control Module which controls output which is powered by a fusible link (K) which is hot all the time

c68
I am not sure that the c68 option is the same but if all other speeds except high is working i would think blower motor resistor is bad. If it has one it would be above rt valve cover on blower case.

Blower speed controlled electronically by blower control module mounted in top of A/c ducting in engine bay
