Question about GMC Yukon

1 Answer

When there is high humidity, the Yukon refuses to start. If I put a fan under the hood, it usually starts after awhile. I have replaced the dist. cap and rotor twice, but this does not help. The problem is even worse now that the Yukon is in Oregon!

2005 gmc yukon fan relay location


In the under hood fuse / relay box ! There are three of them COOLFAN/relay 1-2-3 . It's marked on the under side of fuse box lid .
The engine cooling fan system consists of 2 electrical cooling fans and 3 fan relays. The relays are arranged in a series/parallel configuration that allows the powertrain control module (PCM) to operate both fans together at low or high speeds. The cooling fans and fan relays receive battery positive voltage from the underhood fuse block.

1994 camry won't start after cleaning under the hood check dist. cap replaced spark plugs sounds like its going to start then doesn't.


Sounds like wet or moist spark plug wires. If this also occurs during early morning high dew point humid air, then you may have spark plug wires shorting out.

Replace wires.
