Okay, I give up, I have a 95 Blazer, spent hours trying to find out if there is a master door lock relay and where it is located,I have researched many hours. The answers are from right hand side of steering column, passenger side [hard to find], there isn't one, etc.
Can anybody give me a definitive answer to my door problem. I can open driver's door with key, only then can I open rear hatch, eithor by dashboard switch or actual hatch button. The master switch does nothing, I replaced that, still the same. From info. gathered the next step was to check the master relay, there my problem begins, is there or isn't there one, if there is, where is it located, or are there any other suggestions, many thanks.
