Heater Switch

[89Suburban]

So I got my new switch from RockAuto. Looks great. Put it in today and fixed a blown dash light bulb while I had it apart.

Pulled out heater unit as far as it would go. The vacuum hose connecter felt like it was fused to the housing so I didn't fight trying to takk it off and risk breaking something. Just had to unplug the backlight bulb harness and it came out far enough to get to.

Plugged in the new switch. Each one of those wires in the connector engages 4 different brass strips that run into the switch housing. The old one I took off, the feed strip from the power wire was black and thin and ready to burn into nothing. I threw that out before I could take a pic. The wire and the connector looked ok. Hopefully this switch will be good for another 180,000 mi.

There is one screw that holds the switch to the housing, of course the head of it faces the front of the damn truck, so real bitch to get to it. Had to break out some trick tools, thank god for them, right?

Another tool that changed my life for the better. I want this Makita buried with me when I depart this world.

While I had it apart, I wanted to replace the Service Engine light bulb, it stopped working and I figured it was the bulb, and it was. More fun taking the dash apart and putting it back together. Nice time to also wipe down the guages and the covers too while it's apart.

As always, big fingers and little screws in a dashboard are a comination perfect for aggravation. This little scew I dropped behind the dash finally showed itself after I fist slammed the bottom of the dash a few times.

I hope Bearpigman moves this to the technical part as a writeup. Your dash is incredibly clean man. I really dig it!

 

[Old77]

Yes, more pics the better! We're very visual!!!!

Can I get a really big favor?

Can you measure the face (height & length) of the HVAC controls for me please???

Can I measure it with the dash bezel in place? I REALLY don't want to take that off again.

Did you have to remove the gauges from the cluster to get at the bulbs or do you just like taking stuff apart? On my 85 the bulbs are accesable from the back of the cluster, they are in those little turn lock sockets. If you have to remove the gauge to replace bulbs on the 89 they really screwed up the dash redesign IMO.

I already had the dash apart to do the heater switch. See, on the models with AC, there's a lot of **** in the way to reach up from under the dash to try and get to those bulb sockets on the back. I'd rather sit comfortably with a screw gun and do it from above. Plus, I got to open her up every year for inspection.

Great Write Up and Pics.

Oh yeah !!! Pics are the bestest. Always makes the reading more enjoyable and the write up much eaiser to understand. And especially the tips about hidden screws and crap like that. Major big help in areas like that. You get enough write ups in one place, you can put Haynes and Chilton out of business. Now you need to share your hidden folder of pics with us !!!
