Pontiac Repair: 2005 grand prix, blower motor resistor, shock absorber

Question
QUESTION: hey todd another problem with the blower motor or resistor. i replaced the main 4 fuse and resistor motor, all worked fine for 1 day. now the blower works intermittently, any ideas why it would do this now?

ANSWER: when you say it woorks intermittantly do you man that it just cuts out for a second and comes back on or it just plain stops or will not work? If it just cuts out for a second there is a fix for that you need to insert a capasitor between the power and ground to the blower motor resistor. If that's not the issue you need to catch it ben it's inop to see what your missing. Does it blow a fues still? It could have a bad motor causing a big draw or a chafed wire.

QUESTION: it stops all together, maybe i should replace the motor and possibly the power wire from the main 4 fuse?

ANSWER: What makes it start up again? does it stop for more then a split second? If so then like I said you have to catch it when it stops to find out what your missing you could have a bad ground problem as well. Do this when it cuts out does/do the wiper stop as well or does the use of the wiper make this happen? if so it needs that capasitor I was talking about.

QUESTION: it does happen when I use the wipers some times.when i went and tried it after about 15 minutes it worked again

Answer
Try the Capacitor thing first and fore most. here is the part # 25073556 or stop at a radio shack and get one that is marked 300 uf 50V The uf is micro farads. it goes in between the red and black wires going to the module it's self.Solder it to the wires. There is an arrow on the capacitor it faces towards black wire. It's a cheap fix and I have done a bunch of these but usually it's a momentary storage of the motor. It stops the module from voltage spikes basically a capacitor is an electrical shock absorber/battery It will continue to supply voltage if there is a drop or it will absorb any spike in voltage. good luck
