My 1997 Pontiac Grand Prix
replaced seized blower motor and faulty resistor
comments = Dear JK: blower motor works only on high mode the lower
modes do not work and also its affecting the daytime driving lights when
blower speeds is used
JK:
Hello and welcome. Could you please give me a little more info. The
>blower motor was seized, and the resistor was replaced. Did either show any
>signs of corrosion or discoloration at the electrical connectors? Any other
>odd electrical problems before the replacement of these parts? Any other
>info will be helpful.
> Thanks and I will wait for your reply.

Blower Motor Only Works on High
Visitor reply:
no corrosion at all on terminals what its doing is this problem was their
before the blower and resistor was replaced. The problem was the DRL
lights go off when blower motor switch is used and go back on when the
switch is off. Also the blower motor only works in high mode after a slight
delay. What im hearing is the relays clicking in the day time driving light
module when the blower switch is used. Thanks any questions let me know
thanks

OK, i think i found something to be of help. After looking through several wiring
diagrams, i have found that the Daytime running Lights Module and a power input to
the a/c control head share the same fuse (DIC/HVAC) There is also a DRL diode in
the system. The module and the diode are on the lf. side/under the dash. We need to
find out which part is clicking erratically. Apparently there is some electrical back
feeding going on, and effecting the DRL/headlights. I wound suspect a faulty DRL
module, but the diode may be the original problem, causing the module go bad. Hope
this was helpful. Let me know what you find......
