what does the engine compartment fuse block control for 1990 buick reatta
Many things. It's primary function is to distribute power to the smaller fuse box inside the car. It also contains relays for the fuel pump, radiator cooling fans, etc. HTH. - Jim
The only fuses in the engine compartment of a Reatta are in the relay center just in front of the air cleaner. Only two fuses there and they are for the headlight motors. ....everything else in there are relays and there should be a label telling ;you what they are for.
