Question about 1999 Oldsmobile Intrigue
My blower stopped working on any speed 6 months ago. I had it and the resistor replaced yesterday and after it was "fixed" it "blew" and stopped working. the mechanic replaced the motor at no extra charge and told me of the occurence and hypothesized that the problem may have been the blower modulator causing a spike in voltage. He claimed he had checked and couldn't find any spikes but wanted me to know in case it reoccurred. As I was driving home the heater blower was working fine and then I heard a "pop" the blower still works but I called the mechanic and he said when it broke for him he heard the same thing and it stopped working completely. Does his suggestion sound reasonable and if so what might it cost me since I have already spent $500 for the above repair and a new battery?

SOURCE: rpm`s spike up and down
I don't wanna laugh but the Vibration of the defrost is probaly wiggling a connection --most likely a harness ground on the engine bay firewall ---I'd check the grounds then the throttle position sensor connector connection and then the --Don't laugh distributor connections to inlude the engine to cab ground cable ---braided bare cable from the block to the firewall -
--the COIL pack may have a poor connection ---and I believe if correct on blazers the feed wire to the coil from the harness
is thick and pinkish that connection if loose describes the symptoms exactly
nothing works without a sufficient GOOD gound --loosen and retighten and ground wires-positive wires and connections ----GM is well known for wiring harness problems ---my 84 blazer
happened to share the same ground for the Blower motor and the distributor ---not anymore!
check your connections and those grounds --am I repeating myself ---and also continue to seek help in here if still persisting after that ---should only take 15 minutes to check it all
30 to fix most likely
hope this helps

The blower is on the right hand side under the dash. You are right in thinking the blower resistor is the problem. The resistor is in the heater box behind the blower. Only 2 bolts hold it in but the back one can be a challenge to remove. The bolt is 5.5 mm.
Check for power and ground with a test light at the resistor connector. You should have power on the colored wires in the various switch positions. The black one is ground.
