OK heres the scoop on the 95 model year.
I had a 95 and my issues were common but needed top be replaced or repaired. Your RIG is now 13 years old so it needs a bit of help.
1- Ambient Temp Switch
2- Brakes
3- Power Steering Pump
4- CTIS Plumbing
5- Heater Core (OUCH) you cannot even get a 98 or earlier HVAC system the cost of replacment is $1500. HUMMER or any Hummer parts replacment place will NOT I repeat SELL YOU a older HVAC system unless its used. (Good Luck ever finding that they are like Gold lined with Silver)
BEWARE BEWARE BEWARE............
6- Geared Hub Seals (Ouch again) needed however.
7- Windshield Washer Pump because the 95 washer pump SUCKS.
I can spit out my window farther that that stupid thing spits water on the window.
8- Window Frame Seals - you will see why
9- Windshield Frame Seal "Ditto"
10- All your marker lamps should be replaced as well they are all pretty corroded. Expensive to replace. GET LED ones if you do replace them.
11- The Door locks suck. Get them greased up real good and they should work better.
12- The Power Windows go up SLOOOOOOW because the Window frame seals are usually shot. Hence replacment
13- Keyless Entry is goofey
14- Door lock actuaters usually need replacing as well.
15- UPGRADE to 2001 Mirrors is a MUST. The previous mirrors suck all the way around.
15- SO much more to list........ However when I got done fixing my 95 it was working and looked like new. It cost alot to get it thier as well so choose your mods and upgrades carefully. When you own an H1 it is costly and unless you dont mind it in the shop at least once a month than I say go for it. However by the time you are done with mods and ups you could of bought a 6.5 TD 99 and newer. I myself have owned 3 H1's and would NEVER EVER buy any other year earlier than a 2003. My other posts list the reasons why the 03 and later are important.
GOOD LUCK
