'02 4dr 4wd, 93k miles: engine starts within a second of turning the key, idles fine, goes down the road find, gets about 17-19 mpg in combined street highway driving, coolant temp just under 210 mark on gauge with the AC on, running 65mph, 106°F showing on overhead console, oil pressure above 40, steering is fine, ride is good, 4wd works fine as well.....

So what do I do?

 

Lanny I'm not getting it, are you saying your A/C is not working. Its unclear what your asking. On mine the console reads the outside temp but that's a 95.

 

Lanny, if everything is working fine then I'd be very carefully saving your pennies and keeping your head down cause all h#ll will likely break loose soon. There's always something broke/old/worn out on my Blazer that needs replacing.

 

Give it time. It will come.

 

Lanny, if you don't have enough to fix on your own rig you're welcome to head north and help me work on mine.

 

spittybays: the AC works fine...nice and cool, nothing wrong with it

So I guess the answer to my question is....nothing....well guess I could wash it...then maybe it would rain here, not likely for another three weeks, but ????

I just keep driving my '02 Blazer and all is fine with it. I sure wish it had a 5 sp manual transmission though......I prefer a clutch and changing gears.

Saving my pennies though.....and guess I should go see Toby and work on his......

 

Yes you should. I have a fridge in the garage. I'll stock it with the beverage of your choice. It's only about 1600 miles up here from Tucson; no problem for someone with a Blazer in such great shape!

 

I would strip it down bolt by bolt for no reason and reasemble

 

Just noticed that the cat is rattling when in gear and foot on brake. Verified it is the cat by hitting the cat with my hand and yep....it has broken loose inside.

Sooooo....I have something to do; I can either cut the old cat out and have a universal cat welded-in or buy a new Y pipe and just bolt it in. Much cheaper to cut and weld but will have to take to a shop as I do not have a welder or know how to weld. (Could be a good time to learn though....).

 

I am not really sure the point of this thread LOL
But trust me, gloating at how well its running, I swear, these trucks can sense that, and something will mess up.
