Your system works a tiny different. No separate circuit for high only. The blower resistor / controlmodule controls every speeds, and also the ground for the blower- circuit 2150 BLK wire. Have to put the voltmeter, or far better yet a check light, in the blower connector. Check light will certainly light if you have power in andground. Sounds choose you probably won"t.

Sounds prefer the resistor / module is bad. Also check the plug on the for shed terminals. The modulealso has a floor behind the radio top top the overcome beam.

Anyother odd electrical problems prior to the replacement of this parts? any other details will it is in helpful.Thanks and also I will wait for her reply.

Visitor Reply:no corrosion at all on terminals what its doing is this problem was their prior to the blower andresistor to be replaced. The trouble was the DRL lights go off when blower motor switch is usedand go back on as soon as the switch is off. Also the blower motor just works in high mode after aslight delay. What I"m listening is the relays click in the work time driving light module as soon as theblower switch is used. Thanks any kind of questions allow me know. Thanks.

Answer:OK, ns think i uncovered something to be of help. ~ looking through several wiring diagrams, ns havefound that the Daytime running Lights Module and a power input to the a/c manage head sharethe same fuse (DIC/HVAC) there is likewise a DRL diode in the system. The module and the diodeare top top the lf. Side/under the dash.

We require to uncover out which component is click erratically. Supposedly there is some electric backfeeding walk on, and effecting the DRL/headlights. I wound doubt a faulty DRL module, butthe diode may be the initial problem, bring about the module walk bad. Hope this to be helpful. Let meknow what friend find.
