DIY - How to get interior fan working again /w heater bypass tube
All,
If you have the rs heater bypass installed or removed the heater blower, the interior fan won't run unless you have the temperature set to the blue dot.
Searching through RL, one of the solution was to connect 12V to the G1 & G19 of the ECU. There is a relatively easy way to do this. Just make a jumper to jump pin 30 to 87 on the heater blower relay (relay 5) in the engine compartment fuse & relay box.
Below is a pic of the jumper (circled in blue). I only jumped one of the pin, but the interior blower seemed to work just fine.

You are my hero, I just did this and it worked like a charm! I was regretting doing that tube because the defrost went to crap. Now I'm back to normal, thanks a bunch!

On the fuse box diagram, remove the relay labeled number 5 and put the jumper from pin 30 to pin 87. It's the horizontal middle slot on the right to the vertical middle slot on the left. Easy day. Make sure to pull the 30a fuse so the connector for the blower isn't hot.

this worked great, thanks for the info. I aswell installed the correct jumper relay pn 964.610.184.00 and pulled the fuse #11 (30amp) now its time to install the 993.211.941.00 bypass tube with 964.106.403.02 fan duct, Go figure most 95 also have the updated 96-98 fan duct pn 993.106.403.00
