#6 of 16 right side rumble by shifty3y3d May 03, 2007 (5:20 pm)
I have a 98 Jimmy and when I get around 30 mph I get a rumble on the right side of the truck. It stops when I turn to the right like if I'm on the interstate but as soon as I straighten out it starts again. Does anyone know what it could be? Replies to this message: repairdog (May 04, 2007 3:27 am)

Replying to: shifty3y3d (May 03, 2007 5:20 pm) Check your hubs - sealed 1 piece bearings in the hub that may be failing. If you have a floor jack and jack up under the a-arm if a 4wd so CV axle does not bind you should feel/hear grating - jack it up anywhere on a 2wd as no CV. If thats it about $150 for a hub and have to have an 18mm wrench for brakes, a 36mm for 4wd nut, and a 2 jaw 6" puller for CV if 4wd. Dirty job so get the cardboard out! 2wd is much faster!
#8 of 16 2001 Jeep Cherokee Blower Motor Not Working by nvtitan May 04, 2007 (2:56 pm)
I have a 2001 Cherokee Sport and over the past 4 months the blower motor would cut in and out. Last week the motor stopped working completely at any speed setting. I spent several hours browsing the internet for simular issues and found some ideas as to how to troubleshoot. I was about 10 seconds from replacing my blower motor resistor before I had one last weak attempt to avoid the cost. I lifted the hoop and located the blower motor on the passenger side. I then firmly grabbed the electrical conector and wiggled it back and forth then pushed it down firmly to re-seat it. Now the blower motor works. Only time will tell how long this will correct the issue but it did save me $110 in parts that did not require to be changed.

#10 of 16 Blower and Power Windows don't work by ncdave Jul 28, 2007 (6:28 pm)
I have a similar problem with my '97 Jimmy, but it only occurs when I start up. Usually everything works fine. But intermittently the ABS light remains on. While it's on the blower and power windows won't work. This lasts from a few seconds to over a minute. As soon as the ABS light goes off, the blower and power windows work. Sometimes during this the brake light also comes one. Sometimes the ABS light will flicker.   The power windows intermittently haven't worked for years, but this pattern just showed up a few weeks ago.   My dealer couldn't recreate the problem.

Replying to: ncdave (Jul 28, 2007 6:28 pm) This is exactly my problem. I isolated the problem to somewhere on the hot side of the fuse block. I then removed the fuses for the power windows and blower motor and hot wired them. The power windows and blower motor now work with ignition key off. I now have to remember to turn the blower to off when the ignition is turned off, no big deal considering the alternative.
#12 of 16 Blower motor & windows wont work by bitter Jan 19, 2008 (1:28 pm)
I have a 97 S-10 Blazer with 60k that has an intermittent elcectrical issue with the blower motor and windows not working. The ABS and brake light flash on and off across the dash as if it is doing a systems check while driving the vehicle. At the same time the blower motor stops working and the windows wont work. Now, it wont start at all. The dash lights do not come on when you turn the key in the on positition but the engine turns over. I was getting a multiple misfire code with a high rpm slugish response and hard starts prior to this debilitating issue. Major tune-up did not remedy the situation. I, too, have the dexcool rust issue. Had it at the 37k mile mark. Any suggestions?

Replying to: ncdave (Jul 28, 2007 6:28 pm) ...I have the same problem with my 97 sport S-10 Blazer. What did you find out for the problem?

Replying to: johnnybo (May 19, 2007 9:09 am) Did you ever find the solution to this window/blower intermittance problem? Bitter wants to know. I have a 97 blazer with 60k on it all highway miles with nothing but problems with this vehicle. Dash lights wont come on when you turn the key in the on position and it will not start at all now, engine turns over, but wont start. Pretty sure it is electrical. Help if you can.   Thanks Bitter
#15 of 16 Heater blower / rear defogger/ automatic temp. control by chgoblazer Jan 21, 2008 (9:15 pm)
My rear defogger and blower motor would not work. It was a intermitten problem. I removed the controls on the dash. That is one unit and is a printed circuit. For some reason when I removed and probed the connector in the back, it made a connection and started working. Not sure what happend , but it nows works. \There severals items to check, 1st the fuses. If good run a hot directly to the blower motor , to check if that is good. The plug with 2-3 wires.  Then check the connection behind the controls behind the dash, which has to be removed, not as hard as it looks. total of six screws. The whole assembly pops off after the screws are removed.Don't forget a the five screws under the dash on both sides of the steering column. If those connection are good (orange always hot) Check the resistor for hot , it is attached to the blower motor under the hood. the resistor send current to the blower . Recap Fuses Control under radio , behind the switches ( fan,temp, vents) Resistor. Blower
