BILLS04SS Posted December 22, 2008 Report Share Posted December 22, 2008 Thanks for the info Fireman31 I had the same thing happen to me and it was the resistor as well. A year later It happened again. Must be an issue with our trucks Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted December 22, 2008 Report Share Posted December 22, 2008 I had the same thing happen to me and it was the resistor as well. A year later It happened again. Must be an issue with our trucks It is but it isn't, many times when a resistor goes bad it also cooks the harness/plug that plugs into it. Depending on the shop/mechanic making the repairs, they don't always check the harness/plug to see if it's burnt. So over time, the damaged harness/plug will burn the new resistor out again. Check out the resistor and harness on yours, I would bet that the harness/plug is cooked..... Quote Link to comment Share on other sites More sharing options...

Thanks for all the humor and info..Fireman31 have you fixed this yourself & where would I find the harness & risistor? In the dash or under hood, electrical not my thing but can usually figure it out. Quote Link to comment Share on other sites More sharing options...

In the dash or under hood, electrical not my thing but can usually figure it out. No I have not repaired this personally, but I do manage a 30 vehicle fleet of all Chevys. I have seen this issue 2-3 times in the last year. We switched repair shops around 1-1/2 years ago, and our current shop found some shoddy repairs by the previous mechanic(this resistor/harness issue being one of them on some vans). The blower motor and resistor are in the dash, and when it comes to replacements I would only use genuine GM or AC Delco parts.........

JimJenson Posted December 27, 2008 Report Share Posted December 27, 2008 My AC/Heater only works on 1-4, I'd imagine i have the same problem as those above. Now for the million dollar question, where is this thing located, and what does it look like? Would like to get it running on all speeds.

He'll I wish I could do this myself as mine is out of warranty Quote Link to comment Share on other sites More sharing options...
