The relays under the rear seat of my Buick le sabre 2003 vin 1G4GR54K33U140439 is getting hotter and hotter. The more you drive the hotter they got. The grounds are well, checked by a technician. I don,t drive the car too far, becuase I am afraid that it will cause a burn inside the car, Please help me

heat is normally caused by poor connections either in the relay socket or internal to the relay because they build up carbon inside them as they get old.

Disconnect the battery, pull the relays and clean the contacts in the fuse panel. If the relays still get hot, replace them with new ones.
