Blower circuit[ALL/1998] posted by Scott Mitchell on

Hello, Technical Question: When I use the A/C or heater the fuse for the blower gets very hot. The fuse does not blow but the surrounding plastic on the fuse panel has melted. I understand the blower motor has an internal resistor circuit. Is this wher e the problem lies or perhaps in the blower motor itself? Here's more info:
Model:740 GLE Year '88 Motor:Standard 4 Cly (non turbo)
Your help will be greatly appreciated.
Scott

Scott There was a TSB discribing a repair for this condition, but I believe it was intended for slightly earlier year models. The correction involves making a few wiring changes under the fuse panel and installing an inline fuse for the blower motor. This should be done by some one familiar with electrical repairs. You will also need a wiring diagram. I have seen this proceedure done wrong and cause severe overloading on other fuses and circuits as a result. The current draw on this circuit should also be checked, but most likey will be OK. The overheating in this area was probably caused by a slightly loose connection under the fuse panel. Robert

Ditto what Robert listed , but it would be wise to have the blower current consumption checked. Since the car is approx. 9 yrs old the blower having worn bushings could be causing excessive current draw and make the fuse carry just under the 30 amps it takes to "blow" it and overheat and deformed fuse holder will result.
