Heater control switch only blows on high.
I never really pictured myself driving a Tracker because its so small. But I love this little Geo. I live in the country and we get a lot of flooding. The Geo goes through mud and water like a hot knife through butter. I was amazed. I encourage everyone to try out a Geo Tracker.
Your heater control switch is connected to a resistor pack, which is a number of coils of resistor wire mounted in a little plastic holder on top of the heater box.
A couple of the coils have burned out, so the low speeds won't work any more. I got my replacement from the local wrecker for $2. Before installing it, I spread the coils further apart so they wouldn't burn out like the last one.
It's a cheap, easy fix.
You are quite right about the Geo Tracker.
I own a 1991 2 door, soft top, tracker. It has serves me well. It is a very powerful little vehicle, that handles very well.
The time has come after many years for me to purchase another vehicle, and am having great trouble sourcing another that is comparable to the performance of the Tracker.
The selling points of this particular vehicle are:
Power to haul large and heavy loads;
a decent trunk space when the rear seats are folded;
Good handling particularly on winding, wet and rugged roads;
A sturdy engine that is reliable,
Easy parking in tight spaces because of size.
My one problem remains the automatic transmssion. Automatic transmissions are great for city and open road driving. However my country it is very mountainous, with rugged roads, and the vehicle goes through a lot of chafing over the hills.
This has caused me to replace the transmission in 1999 and now the new one has failed again. Other than that I would say other parts replacement has been due to normal wear and tear under local conditions.
The tracker went through a category 3 hurricane and kept right on ticking over.
Kudos to a great small vehicle.
I have a 1990 Tracker 2dr Hardtop with the GM built 3 speed auto. Here in Arizona it has proved it’s off road ability many times. As a member of ZOA (Zuks of Arizona) we have found that many members who are building or have built rock crawlers have opted for the 3 speed auto. It just eases up over obstacles rather then having to ride the clutch. I find that in driving it around the city it’s hampered by the auto. The later model autos were a 4 speed Overdrive they are much better in the city, but nowhere as good off road. I have replaced the standard 4.73’s in the differentials with 5.13’s from the manual versions. This means I’m turning around 4000 rpm at about 65 which to me is a little high on the freeways, but gives it a lot more spunk on the streets at lower speeds. It also makes it much better at climbing steep hills.
