#3457 of 3676 strong mildew smell in 1997 GMC Jimmy
Dec 18, 2009 (5:08 am)
I have a 1997 GMC Jimmy. The minute you get in it smells like a wet gym bag. It is nothing I have put in the vehicle or left on the carpet.
I was told by a repair man that worked on it and commented that the mildew smell is from a part that needs to be replaced. Unfortunately, I forgot what it was. He said it is a very common thing with Jimmy's and not expensive. I could do it myself. Has anyone had this problem? Do you know what this part is that causes the smell?? Please help!

Not sure of the exact name or part number, but could it be the filter for the fresh air system?
I have heard of this before, but my manual does not show where that filter is and I would like to know also.
#3459 of 3676 Gas guage and CEL problems
Dec 18, 2009 (6:23 am)
I have 2002 Blazer, 4.3, auto, 4WD, 95K and have had one problem for over a year, the other problems started a couple months ago. I have had different guess's but they don't seem to fit or solve the problems.
The first problem was the gas gauge. I can have a full tank of gas and the gauge will drop to empty. Sometimes, if I put the shift lever into neutral it will go back to where it should be and sometimes I have to rev the engine up a bit to make the gas gauge get back to where it should be. The only suggestions were, wiring or the sending unit in the gas tank. Oh yes, the trip computer seems to be fairly accurate as far as the amount of gas used compared to the mileage. This bugs me to no end and I could use some help with this problem.
The second problem I need to get solved is a trouble code P0440. Everyone told me it was the gas cap. I had a new locking gas cap on it from the day after I bought it two years ago. I did keep the old cap, so I put that back on and erased the code. It worked for a few days, then came back on.
I don't know if the two problems are related and because I changed the gas cap and the problem was OK for a few days then the CEL came back on, I am thinking it is not the gas cap.
Have to get through inspection son and need to get that taken care of.
One thing I should mention is that the smaller vacuum hoses had to be replaced several months ago. I am referring to the ones that control 4WD, and the fresh air system. They were all around 3/16ths size hoses.
Any chance something could be plugged or another hose that is bad?
The manual mentions the charcoal canister, but doesn't have a photo. It also mentions the EVAP purge control valve and mentions a couple tests, but not in good enough detail (I'm better with mechanical problems) for me.
I posted the gas gauge problem here a long time ago, but probably worded it differently because I got no response at all.

I have 2 problems. I purchased a 1997 Blazer. AS I was buying it the heater stopped. When I direct wire the fan motor to the battery the fan runs fine. I then replaced the fan speed switch and it worked fine for a week. Now it works sometimes and it doesnt work sometimes. I also noticed that the different doors do not open for heat options. I live in upstate NY (16 degrees today ) so i need this to work any suggestions?
Also when I purchased the truck it needed a new battery. I installed one and after driving 40 miles tried to get it inspected. the mech said it was to soon to read the computer and told me to drive it more. 3 days later the service engine light went on and stayed on all afternoon. The next morning the light was off and has been since. When I reached 145 miles I tried to get it inspected and again the mech. said his message still read not ready to read. I have noticed small electrical items not working IE compass is backwards, gas and temp gauge dont seem to work, could they all be computer related?

Not a filter, the evaporator core drain is plugged. Water collects where it shouldn't and you get mildew. Easy way to tell is on a warm humid day, turn on the ac and see if you get any dripping under the car.
Fairly common problem, the drain just needs to be cleaned. I know it is behind and below the dryer (that big silver thing by the firewall) but I can't tell you exactly where.

emydee23, did you every get your blazer starter replaced? I'm in the process of replacing my 1998 blazer 4x4 starter now and cannot figure out an easy way to unbolt the wires connected to the solenoid.
After a bunch of twisting and moving around, I finally got the starter to a point to where I can pull it out, but it wont come out unless the wires connected to the solenoid are disconnected. How in the heck do you get a socket to these bolts?
#3463 of 3676 4 WD not working on 95 S-10 blazer
Dec 19, 2009 (9:00 pm)
I've read a number of posts about the vacuum lines, but nothing happens when I push the 4HI or 4LO buttons on the dash - no clicks, no nothing. The 2LO and 4LO lights on the buttons didn't work when the 4WD worked last year, I get that they may just be burned out. The 4HI light still turns on and off when pressed. So is this still a vacuum problem? There was another post that there is a separate electronic control module that controls the shifting between 2 & 4 wheel drive that may need replaced. Should I look to replace that first? It just snowed here about 15", but better late than never.

Did you get it fixed?

This fan problem is the same on the 97 Jimmy. I live in Calgary Ab and It hit -34.6 degrees the other day and sure enough the f-ing thing stoped working. I have tried switching out the speed switch as well and its not that. I think it is something wrong with the fan its self. Somtimes if you do not use the fan for a while like me (never use it in summer at all) it tends to build up with crap and doesn't work. Problem is that in the Blazer as well as the Jimmy you have to cut away at it to get in there and patch it up after. Not sure if thats your problem but it worked for mine. Good luck man.
#3466 of 3676 2000 Blazer pulls left and right on a bumpy road!HELP!

Hi guys I've got a problem with my blazer?This problem is not so bad that I can't drive the truck or anything like that.The truck rides very nice on a smooth road.It pulls to the left just a little.Now when a get on a road with a lot of little bumps or potholes it kinda cuts left and then back right and can be kinda difficult for some to drive.REMEMBER this not terrible but not 100% right,it's maybe 90% percent right.Its like the steering is a little loose or something?I dont know if this is a steering stabilzer,ball joints,tierod ends or maybe even shocks which the truck NEEDS REALLY REALLY BADDDDDD!!!!!!!!!!!!!
