I tried to leave work last night and when I started the '87 Vanagon w/ manual trans, the pedal seemed stuck. I gave it a little more pressure and then it went to the floor. I checked the throttle at the engine and it wouldn't move. It was in the teens and single digits last night so I thought some water got in there somewhere and then froze. 
 
I was able to get the van into a heated garage nearby today and I took the cover off where the pedal mechanism goes underneath to the cable. All seemed ok- no water, nothing frozen. Just to be safe I cleaned it up and put some grease on everything under the cover and replaced it. I also lubed it at the throttle.
 
I went home and did a few more things and went to leave again a few hours later- with the same problem! Pedal goes to the floor and stays there. What am I missing? Could something be sticking on the cover over the linkage underneath? While I'm at work I put a heater inside and a lamp underneath aimed at the cover over the linkage to see what that does. If that does it, what was frozen. If not, where else should I look? 
 
I've had too many problems already with this van. I'm getting too frustrated. 
 
Thanks,
Ed in (now cold) CT
