Fan motor problem escalate's.97 LS400
1997 Lexus LS400, recently bought,< "the car, not the fan" condensor fan (not original problem) came on when car turned off ( cold engine) Main problem, blower motor not coming on. Blower motor works when connected to 12 volts. Suspected module, replaced. No signal to module. replaced heater relay, cked all fuses. Have reason to believe there are relays Involved I dont know where they are. Another strange thing is that there are a whole row of fuses (under dash) seemingly unrelated to fan that dont light up w/ test light (key on) locations 12,13,14,15
Now, car will start, dies within 5 seconds unless you keep gassin it. acts like fuel pump. Maybe something to do with 12 volts at start/7-8 volts all other. <does this work thru same relay???
Also relay center....it appeared some one has been screwing with it. 1 of 2 ten mm nuts removed. So, cked underneath. Upon raising deck, one conn. popped out (great) However, have reconn. all and same prob exist. Is there some sort of reset procedure?? Does any of these snafu's sound familiar when viewed together or any combo thereof.

Yes, I wish I could reformat the problem too. And your right, my post was way longer than I realized. Ive just been working this problem for days and its making me screwy. I dont know where all the relays are located and therefore cant test the way I need to. Where can I find the electrical schematic for the blower, condensor, and the rest of the a/c? all help appreciated. If you need help with Paint restoration and Detail, look me up, Ive got a million hours in all facets of this. Theroad

Thanks guys. Those responses were a scream. I needed a good laugh...Originally, I wrote a very long post which contained dialog that really didnt belong on the forum, as it was a lot of rambling(thought aloud) if you will. The post above was in response to puredrifter's request to reformat. as a result, I condensed the key points as best I could. I realize it is "Heavy indeed" none the less, the symptoms are as described, and being aware that forums such as this one can potentially be loaded with experienced and knowledgeable folks who, having many hours of time put in on the same types of cars, can often recognize symptoms and make suggestions on how to correct them. .....theroad
