IF the light is on and flashing, there's a trouble code stored in the computer. Get the code read. Do NOT buy this vehicle until you know exactly what's going on.

There are doors in the plenum that open and close to redirect flow.There are vacuum and electric motors that control them or could be your switch.

Is the check engine light on? See what it says. It may be transmission related. The leaking fluid is probably transmission fluid. If it's really low you'll have a problem.

It may be the switch is failing and needs to be replaced. However, it is not unusual for the motor moving the seat forward and back to jam on the running teeth attached to the seat. If, when you use the switch, you can either feel or hear the motor trying to run, then it is probably a mechanical problem under the seat. This can have a few causes - something on the teeth that should not be there, alignment of the motor to the teeth (maybe loose bolts), etc. If this is the case, the only way to troubleshoot this is to remove the bolts holding the seat frame to the floor, then using the motor move the seat as far back as it will go, then tip the seat forward and inspect the motor and gears underneath.

Can you turn the crankshaft by hand? Use proper size socket and breakover, hopefully, there is a pulley bolt on the end of crankshaft. If it won't turn, take the belt loose and remove spark plugs in case of hydrostatic lock, fluid in the cylinders.
You said it locks-up, that what I am going by. Meaning the engine mechanically locks up. It could be internal engine problem?

I don't believe there would be a problem due to fit but this is difference in measurements.
The 75 diameter (across tire) is 28.88 in.
The 70 diameter is 27.95 in
The 75 width of tire is 9.25
The 70 width is also 9.25
The 75 circumference 90.72
The 70 circumference 87.82
The 75 sidewall height 6.94
The 70 sidewall height 6.48
The 75 revolution per mile 698
The 70 revolution per mile 721
The 75 speed at 50 and the 70 is 48.4
I can't see why it would not work.

Hello Cjmm,

Your vehicle presently has 37 Technical Service Bulletins
(TSBs) Driver Amenities: Instrumentation.. None specifically
point to your issue (not even looking at "tow" issue)...
but the associated wiring clearly depicts
"a continuous battery source"... which should supply
continuous battery during ignition key operation...!!

>> Assuming all battery & ground points are clean
(battery cables & post connections are the FIRST
in ALL ELECTRIC anomalies)...

>> The NEXT is
Fuse terminal ("hot at all times") Fuse 19, 15 Amp
source on your vehicle's wiring diagram.

FREE wiring & TSBs
are available (after registration)
at BBB Industries website for most POPULAR USA market vehicles (I am using it now to verify your "IPC" connection).
See BBB Industries (at bottom):

After FIRST cleaning your battery terminals...
Place FELT WASHERS to prolong protection:
Amazon com Road Power 0989 Anti Corrosion Fiber Washers 1 Pack 2 Washers 6...

Amazon com NOCO NCP2 CB104S 4 Oz Brush On Oil Based Battery Corrosion...

... and remember those cables have two ends...
Them move on to inspect that fuse ...

Amazon com Bussmann DIA 2 ATM Blade Fuse Diagnostic Kit Automotive

Hope this helps

I would recommend replacing the idle air control valve. Refer to any of the many YouTube videos on this subject and you shousl have no problem replacing it. It is availabe at Rock Auto, Parts Geek and most good local parts shops.

Driver side door is used most.Check for broken wires...

2001 GMC Jimmy | Answered on Jul 03, 2017

Do you have the 4.3L engine with spider fuel system? That system is noted for problems. Key on engine off, fuel pressure, 60--66 psi, use a fuel pressure gage. It needs that pressure to start, after it starts, it will run with less pressure.
There could be other issues? Engine cranking, you have spark at the plugs and fuel injector pulse?

2001 GMC Jimmy | Answered on Jun 26, 2017

it will be burnt wire and around the ignition switch
burnt wires are obvious but be smart
only an accredited auto electrician should be used to locate the wire/s so don't let your boyfriend start or it will cost more in the long term and will still not be fixed

2001 GMC Jimmy | Answered on Jun 08, 2017

Check under the hood fuse box for trailer and vehicle fuses.Use a test light and check all fuses in place.Turn ignition and light switch on when checking fuses.

2001 GMC Jimmy | Answered on Apr 30, 2017

Sounds like you have a bad ignition switch, not the lock cylinder but the switch itself. Electrical power should continue to go to the gauges and to the ignition module even with the key in the Start position.

2001 GMC Jimmy | Answered on Dec 07, 2016

Usually not. If it is shuddering while accelerating it's usually a plug wire. If you have a check engine light on then start there
